I’ve always felt that given a suitable environment, clothes should be optional. They’re a tool for specific purposes — sunscreen, insulation, keeping paint off the skin, that sort of thing — and a mode of decoration if you happen to want to play with them that way. And they do make hiding some reactions easier. Other than that, it’s all social conditioning.

I can imagine that Nudge’s crazy antics became very dear to poor, lonely Shellinx.
Phix’visits might have been enlightening, but she still is a bit of a dark character.

Nudge, on the other hand, is like the jester that really loves his King, but is not beyond pulling his leg.
When still part of Tina, Nudge was always the one to get the somewhat moody demons in gear, albeit by singing “On top of spaghetti”, and Nudge has shown nothing but love and dedication to the Wapsi-Gang.

But, well, as a pranker myself, there is NO way that she is able to resist an opportunity to prank people, but she only pranks the ones she actually likes.
