Beastro Boss Guide: All 7 Bosses and Unlock Order (2026)

Updated 2026-10-05: Steam's live achievement API now lists the seven boss-defeat entries at 50.8%, 41.6%, 29.9%, 20.0%, 17.9%, 16.0%, and 13.1%; its name is Terroreyezor, while the v1.0.5 patch note spells it Terroreyzor.

TL;DR: Beastro has 7 confirmed bosses, tracked by their own "Defeat" achievement, in this order by global unlock rate: Flamatito (50.8%), Furrog (41.6%), Cranbear (29.9%), Clobboarer (20.0%), Maracalotyl (17.9%), Terroreyezor (16.0%), and Pokosh (13.1%). Furrog through Pokosh are documented, at least loosely, by community sources. Flamatito and Terroreyezor currently have little documentation beyond their confirmed achievement entries.

How many bosses does Beastro have? (quick answer)

7, not the 5 that circulate in existing community guides. Steam's live achievement percentage data confirms 7 separate "Defeat" achievements, one per boss, and an 8th story achievement ("Beat Clyde") that uses a different verb and isn't included here as a monster boss without further confirmation.

Key takeaways

• 7 confirmed bosses, each with its own Steam "Defeat" achievement, verified directly against live achievement data.
• Order by global unlock rate (a reasonable proxy for story order, since later content is reached by fewer players): Flamatito, Furrog, Cranbear, Clobboarer, Maracalotyl, Terroreyezor, Pokosh.
• Flamatito and Terroreyezor are the two most-overlooked bosses. The current community monster page stops at 5 and does not list either one.
• Pokosh is very likely the final boss. Its unlock rate matches the game's "Complete Final Sealing Ceremony" achievement almost exactly.
• "Beat Clyde" is a separate achievement, not included as a monster boss here since its wording doesn't match the pattern the other 7 share.

The 7 confirmed bosses, in order

1. Flamatito (50.8% unlock rate)

The least documented boss in the game. Flamatito's Defeat achievement has the highest unlock rate of the seven, which places it earliest in a typical playthrough, but the sources checked for this guide confirm only its name and achievement entry. Its attacks and encounter details are not documented here because the available sources do not establish them.

2. Furrog (41.6% unlock rate)

Tied to the achievement "A Furocious Enemy." The community monster page labels Furrog Umami-aligned. Steam's separate "A Problematic Minnyen" achievement is described elsewhere as defeating a Super Minnyen, so it does not establish a Furrog variant. This is the earliest boss with any real community documentation.

3. Cranbear (29.9% unlock rate)

Tied to "A Sticky Situation," whose public achievement description identifies Cranbear. The achievement and the current community page do not document a precise sticky or card-binding effect, so this guide does not infer one.

Oyshi's deck screen shows the pre-fight setup: cooked dish cards and flavor cards are assembled before a venture battle.

4. Clobboarer (20.0% unlock rate)

Tied to "Rubble Rouser," whose public achievement description identifies Clobboarer. The sources checked here do not document a rubble, area-effect, or debris mechanic, so the achievement title is not treated as a mechanic description.

5. Maracalotyl (17.9% unlock rate)

Tied to "Shake it Up!" Steam's achievement identifier uses "Maracalotyl," while third-party achievement descriptions commonly render the monster as Maracalotl. The sources checked here do not confirm a hand-shuffling or reordering mechanic.

6. Terroreyezor (16.0% unlock rate)

The Steam achievement record uses "Terroreyezor" and the official Timberline v1.0.5 patch note spells it "Terroreyzor" when saying its animation was not showing correctly. That patch note is independent confirmation of the encounter, but it does not document the boss's attacks or mechanics.

7. Pokosh (13.1% unlock rate)

Tied to "The Fire Within." The current community monster page identifies Pokosh as fire-using and documents that Sweet cards caramelize instead of weakening when singed. Steam currently shows Pokosh at 13.1% and "Complete Final Sealing Ceremony" at 13.0%, supporting the conclusion that Pokosh is the final boss, though the percentages are evidence rather than an explicit order statement.

GODEEPER: Pokosh's fire mechanic connects directly to Beastro's flavor system. Our flavor guide covers all 6 flavors and how fire/Spicy interactions work outside of boss fights too. Beastro Flavor Guide: Cooking Meets Combat →

Step-by-Step: how to verify a boss list like this yourself

1. Pull live achievement percentages. Steam's GetGlobalAchievementPercentagesForApp API returns every achievement's internal name and current global unlock rate for free, no key required for read access on this endpoint style.

2. Filter for the pattern, not the count. Look for a consistent verb prefix ("Defeat," "Beat," "Kill") rather than trusting that a wiki's boss count is complete. This is exactly how Flamatito and Terroreyzor turned up here.

3. Cross-check the achievement records. Steam's stats page shows the public titles, while the live API's internal B_STORY_Defeat... names identify the seven monster entries. Third-party achievement lists provide the hidden descriptions for entries whose Steam page does not display text.

4. Check official patch notes for anything the achievement data alone doesn't explain. This is how the Terroreyzor spelling and animation fix provide a second, independent confirmation beyond the achievement API.

Regular enemies vs bosses

Beastro's current community monster page separately lists 16 named regular enemies: Minnyen, Bogpiper, Volcano Turtle, Tsunami Turtle, Thorn Wolf, Lava Elephant, Thunder Roar Beast, Honey King Snake, Berry Bear, Grotesque Spotted Shrimp, Palm Wing Bat, Erode Runner, Rancidancer, Catabeetle, Explosive Crab, and Star Ribbon Jellyfish. That page lists ingredient drops for many of them and notes a hidden Spicy interaction for Star Ribbon Jellyfish, but the Steam achievement endpoint does not document each regular enemy's region, drop, or combat attribute.

The community page keeps this roster separate from the five-boss progression it documents. This guide does not infer story-gating or unlisted combat mechanics for these regular enemies from their names alone.

Every ingredient a boss or regular enemy drops eventually runs through a cooking mini-game like this one. The combat and the kitchen are the same loop wearing different clothes.

Why this matters for a "complete" boss list

A roster list built from community consensus alone inherits whatever gaps the community happened to leave. Achievement data does not have that problem: every boss with its own defeat condition appears in the live endpoint whether or not anyone has written a guide for it yet. That is also why this guide does not invent mechanic details for Flamatito or Terroreyezor: their existence is confirmed, but their specific attacks and mechanics are not documented by the sources checked here.

Frequently Asked Questions

How many bosses does Beastro have? 7, confirmed directly through Steam's live achievement percentage data, each tied to its own "Defeat" achievement. The current community monster page names only 5, so it does not include Flamatito or Terroreyezor.

What is the first boss in Beastro? Flamatito, based on its achievement having the highest global unlock rate (50.8%) of the 7 boss-defeat achievements. It is the least documented of the 7 in the sources checked for this guide, beyond its confirmed name and achievement entry.

Who is the final boss in Beastro? Pokosh, tied to the achievement "The Fire Within." Its unlock rate (13.1%) is nearly identical to the "Complete Final Sealing Ceremony" achievement (13.0%), supporting the conclusion that Pokosh is the final boss.

What is Terroreyzor in Beastro? Terroreyezor is the sixth boss by achievement unlock rate (16.0%). Timberline's v1.0.5 patch note spells the name Terroreyzor when describing an animation fix, while the Steam achievement record uses Terroreyezor.

Is Clyde a boss in Beastro? Unconfirmed. The "Beat Clyde" achievement is at 55.9% and uses "Beat" instead of "Defeat," the verb used for all 7 confirmed monster bosses, which suggests Clyde may be a different kind of encounter rather than a monster fight. This guide does not include Clyde as a boss without more confirmation.
