Like a kid in a candy store, Fizz is very excitable when it comes to making – and using – any kind of explosive device. Only his don’t go BOOM. They go SHLOOP, BOING or POOF, and are extremely silly. Sometimes they backfire! Eager to prove himself, this pup looks up to Vi, and is always willing to follow her lead. Sometimes, he follows in the wrong direction! Fortunately, Violet and the other agents are good at keeping this brave dog in tow.
