I gave it the prime rib and it ate it, but now it is just sad because it is all covered in barbecue sauce and is all sticky but he doesn't have any hands to clean himself with. Help!!
Okay, okay, calm down, I'm an expert in these kinds of situations. First off, you'll want to get some prime rib, then toss it down in front of the slime. It should eat it, then be happy enough with you that it'll come out from behind your computer; that's when you hit it with your dragon sword. After that, it should try to join your party; let it. Raise it to level 32 so it learns MegaMagic, then get another slime with at least +5 and breed them together; BAM! Instant SlimeKing pet with MegaMagic and Vivify, along with some other pretty kicking rad skills.
