The I'm Eggscellent Net Hat was seen in Eggscellent. It was seen as the grand-prize for the Eggscellent Challenge and Rigby wanted it. It was seen in the commercial, at the end when Rigby wears it (which revives him), and in the final challenge when it's on the table. There are many hats like this in the closet inside the dungeon room, to replace the one someone took, however the closet was nearly full, therefore, not many people have gotten the hat. Oddly, it appears in the Steak Universe commercial, where an actor wore one exactly like it except the words "I'm Eggscellent" were not shown.
