Rainbow Bob

Rainbow Bob is a Hard Mode miniboss slime that spawns in the hallow when you accept the Rainbow Quest from the Necronomicon. It is exceedingly good at escaping the player.

Behavior
Rainbow Bob will hop around in the hallow. If the player approaches it will flee. It can temporarily turn invisible, jump high into the air or even slide through blocks. If the player does get too close it can summon Rainbow Slimes (Summoned rainbow slimes dont count towards the quest), or it can deal contact damage. If it is in the rain it heals.
