It seems that when Dr. Frogg is stuck in Doomageddon's teleportation/stomach dimension, that it's a sunny rainbow paradise. But this isn't what the realm is. Rather, the realm appears as a person's worst fears. So when the veterinarian at the beginning was teleported to it, he saw a much more typical hellish landscape. It has been shown that Dr. Frogg hates goodness.
- Jossed by the episode Doomhound in Love, which has the group travel to Doom World, and they all see the same Sugar Bowl.
- Also, General Sargeant was there too, and he could see what Frogg was seeing and was enjoying it to the fullest "Let's all slide down that rainbow!!"
