Pinky

Pinky, the smallest Slime, is an uncommon, low level monster found on the surface, in shallow caves, and in the Underground.

It deals 5 damage with every hit, has 150 HP, 5 defense and drops a large amount of coins when killed (almost always at least 1 gold coin, a platinum as a very, very rare drop). It is also noticeably smaller than the other Slimes.
