Stale Cupcake Golem Trap

An ancient lost cupcake from parties long ago. A confectionery guardian in the shape of a delicious cupcake! It sits innocently enough, completely stationary looking deliciously ordinary until something comes across its googly-eyes. At this moment it transforms into a hulking golem prepared to fend off any mousy invader without an invitation!

Keeping parties safe since... We don't even know!
