Has anyone made a Pom Pom NPC?

[The Handwoven Box]

Title. I tried searching on google and didn't find anything, and "pom pom" and "pom pom npc" are too short for the forum search to actually look for them.

Also, has anyone made content from Mario Maker? Like the one way path things, items (the hats or items that go on your head), etc.
