The spell to turn Scabbers yellow is a nonsensical and non-existent spell fabricated by Fred and George Weasley that could supposedly change Scabbers' fur colour to yellow, but does not have such effect, as it is entirely fictitious, and nothing would happen.
Behind the scenes
- It is also possible that the reason the spell would not work is because Scabbers was not a real rat, but was in fact Peter Pettigrew, an unregistered Animagus in disguise.
