Neptune's sun is a sun that appears in the episode "Feral Friends."
Unlike Neptune's moon, which transforms anthropomorphic sea animals into real-life ones, Neptune's sun transforms land animals into either real or prehistoric animals, depending on its target.
Role in episode
It appears at the end of the episode, transforming Sandy into a real squirrel. It also even transforms Potty into a Pterodactyl and Patchy into a caveman when their ship is about to sink. The French Narrator does not seem to be affected by it at all.
- Neptune's sun comes out directly after Neptune's moon sets.
