I'm always shocked that this is the very first episode of the show.
Without any context we are dropped into this insane world of candy people, Sugar craving zombies, reanimated corpses, bubblegum princesses, giant sentient gumball machines, talking dogs, Korean rainbow unicorns ... wow. You would think it'd be Overwhelming but somehow it just works and it's charming. Without any character or world backstory it somehow feels right. Like a crazy sweet sugar rush.
Does a great job of setting the tone for the overall show and its wacky & semi-dark sense of humour and playfulness. Not afraid to discuss zombies, death, flesh eating etc, pretty nuts for a "kids" show.
Being chucked into the world without a guidebook or map is a total thrill ride and an exhilarating journey that leaves you craving more sugar.
