Low Poly Mushroom Monster and Low Poly Mimics & Chests & Loot are now available on the Asset Store, and are part of the Low Poly Monster Bundle. These are low-poly versions of the Mushroom and Mimics/Chests high-fidelity packs.

Do I need to update?
If you already have the Low Poly Monster Bundle, then it makes sense to grab these as they’re included for free. The Mimics & Chests & Loot pack in particular will be quite versatile for your low-poly games.
