The April Wolf Bug

The April Wolf Bug is a sickness inside of Lovely World that is shown to only affect the human-wolf species. 
== Effects ==
Note: This is mainly speculation, as the episode where Charles gets the illness, A Change In Tone, doesn't give direct responses to the effects, so this is going by what happens in the episode before a colour change.
The bug comes from something in the air in April, mainly on April Fools Day. It changes the colour of wolf fur. It starts as red, which makes the victim feel "off", not sick just feel like something is off. The second stage turns the victim's fur orange after they have been in a state of confusion, or underground for a few minutes. The victim also seems to get a bit annoyed at silly antics more often, it's out of character for Charles to be telling his helpers off at their antics. The third stage turns the victim's fur yellow after they have been out in the sun for a few minutes. The fourth stage turns the victim's fur green after witnessing something disgusting. The fifth stage turns the victim's fur purple, either after breathing in microwaved, probably 6-year-old fish, witnessing something disappointing, or breathing in a 6-year-old pizza, it makes the victim feel nauseous and unable to go on tall rides, it also makes them more jumpy than usual. The sixth stage turns the victim's fur white, or pale as said by Charles. It happens at night with no obvious clue as to what causes it to advance. It makes the victim have an attachment to a certain block, when it seems bland, they are keener to turn away to any form of power, like Redstone. The victim also gets more forgetful, as they can't think of who certain people are, or words, making the victim more prone to stuttering and saying sentences and words wrong.
