Clash of Critters Boss Stars: Every Upgrade Milestone
How boss stars work
Every chapter has 8 boss stages (every 10th stage), so 120 chapters hold 960 boss fights and, per the wiki, 601 boss stars to earn. Each star also clears a tile of camp land (the shovel icon) — the star system and camp expansion are the same progression. For the first 14 stars you get one upgrade per star; afterwards one upgrade per two stars. Most upgrades repeat with larger values.

Why it matters for progression
Boss stars are the only way to grow pinball income (trees, depot), candy multipliers and shield capacity — the things that gate everything else. So when a chapter walls you, clearing the next boss stage is worth more than ten normal stages. Boss stages also pay 30+ pinballs, a shovel and sometimes Wishboxes and Silver Bricks, and they cannot be Auto-Battled. See chapters for boss stages per chapter and the Zobo codex for boss mechanics.
