A lot or a little?
The parents' guide to what's in this TV show.
What parents need to know
Parents need to know that Billy Dilley's Super-Duper Subterranean Summer is a fast-paced animated series about three friends who discover an underground world inhabited by strange creatures and eccentric humans. It's imaginative and visually engaging, thanks to the animation style and colorful characters, but there's little substance to the bizarre plots. Expect some potty humor (body noises, nasal discharge, and drooling, for instance), a lot of dramatics from the female character especially, and some moments of mild peril. Billy's interest in science stands out in some of the stories, inspiring his inventions and creative problem-solving skills, but it's not going to teach kids much about the subjects.
What's the story?
Best friends Billy Dilley (voiced by Aaron Springer), Marsha (Catherine Wayne), and Zeke (Tom Kenny) have an unexpectedly adventurous summer when they find themselves stranded in an underground world in BILLY DILLEY'S SUPER-DUPER SUBTERRANEAN SUMMER. It's a land of rock people, furry round monsters, and bizarre humans with odd backstories, and it's a place where just about anything can (and will) happen. For science fan Billy, this means lots of opportunities to invent solutions to his many zany predicaments.
Is it any good?
With adventure around every corner, this new world of Billy's appeals to kids' sense of imagination, even if it does so with more nonsense than anything else. The show is visually pleasing, boasts a talented voice cast, and is filled with nonstop action and laughs plus a fair dose of the bathroom humor that's such a hit with grade schoolers (if not so much their parents). What grown-ups will like are Billy's unfailing optimism and unwillingness to shirk a challenge of any size or shape.
Though only slightly prominent in the plot, Billy's fascination with science does cast a positive light on basic concepts such as inventing as they relate to the stories. There's no attempt to teach anything tangible or present Billy's creative problem-solving tactics in any realistic manner, but the fact that he's interested in designing machines and using science in other practical ways could be a positive influence on viewers.
