Melvin, Teether, and Timmy

Imagine — When Melvin, Teether, and Timmy enters the battlefield, create Bobby, a legendary 2/2 green Bear Titan creature token with indestructible, vigilance, and trample.

When Melvin, Teether, and Timmy leaves the battlefield, exile Bobby.

"Just because I imagine him doesn't mean he isn't real." - Melvin
