Meteor Slime

Meteor Slimes were cut from the game, and the only trace of their existence was in Slimepedia Page of Silver Parsnip before it was added as its favorite.

It was planned to be added in 0.6.0 However, the devs stated that the slime wasn't working. Parts of it will be repurposed for the other new slimes, and it's possible that it might come back in a future update.
