Blastosaurus Vol. 2
A shapeshifting monster dog, a super powered raccoon, a punk show and too many pickles. A mutant triceratops try's to keep all these things in order. It's a big night in Freak Out City when Merle the miniature schnauzer loses the magic collar that stops him transforming (at random) into a giant glowing monster from another dimension. Now he's on the loose and on a rampage trying to track down the raccoon who stole it. Richard feels responsible because (of course) it's his fault the raccoon got the thing in the first place, so he (and Merle's elderly owner Doyle) go to our hero for help.
