Yeah. Wait until you try to raise a jumbotender lul. The evolution rates suck on some monsters.

It can take months for a sabotender to turn into a jumbotender.

If it Squirms it "might" evolve after the irl day change. If it shudders it evolves on zone.

Oh wut?
I thought evolution was "granted"
Daaaamn

It can be, there's 3 things that can happen when you give the evolution item.

Squirm, next day failure.
Squirm, next day success.
Shudder, instant evolution. Zone out and in.
