Peter

As someone named Peter, I enjoyed this puzzle. Except for the clue associating my name with “fizzling out.” Us Peters are persevering folk! No more besmirching of the name Peter!

Got hung up with DEM. I put “DEB” - short for Debbie Downer, who is sad (blue). And JAMAICAN RUB looked ok to me as a known entity, but clearly not a spirit!
