The show uses a blend of American and British voice talent, with actresses such as Tara Strong, Anna Popplewell or Cree Summer voicing high-pitched manic creatures, while John DiMaggio, Tim Curry or Clancy Brown covers deep, comedic roles, similar to the varied casting seen in modern animated television shows where they deliver a letter to a haunted toaster, resulting in a SpongeBob-like 11-minute frenzy of explosions, weird face-pulling, and fast-paced British/American banter, similar to The Rim & Stimpy Show. The show relies on Ren & Stimpy style extreme close-ups, grotesque details, and heavy sound design—"boowomp" for failure, "ahooga" for surprise, "splats," and "springy" sounds.
