Teddy's name comes from the word "teddy bear" referencing his stuffed animal based appearance.
Teddy spawns an army of Chompers at his aid. It’s best to find higher ground to deal with him, such as a vehicle or an elevated platform. Teddy will never use Slobber Shot, but his Chompers might. The most Teddy can do to you when you’re up on higher ground is to use Grody Goop and deal light toxic damage to you.
