Curse of the Mystery Mutt

AAAAAAAAAAAGH! Something terrible is going on, my person-pal! Something so DREADFUL, it's enough to curl your tail with TERROR (if you have one, of course)... A spine-jangling HOWLING has been heard in the middle of the night, favorite toys have been STOLEN, trash bags have been SHREDDED and all the best pee-spots have been RE-SCENTED! It must have something to do with the NIGHT OF THE HOWLY WIENER, which is only days away… Can I find the evil mastermind who is TERRIER-izing our town?!
