Koopa Troopa is one of Bowser's minions. Along with Goomba, he never appears in videos anymore, mainly due to the fact that his plush is used to portray Joseph to this day. He is also an antagonist in The Perfect Plan!
Koopa is very shy and is usually seen alone and only gets called whenever he is called. He first appeared in Koopa's New Job when he says that he hates his job. He has died once (possibly twice) in the series. He was made into turtle soup by Chef Pee Pee. He had a major role in Bowser's Birthday where Bowser tells him to give him birthday spankings and a birthday cake which he asks Chef Pee Pee to make it. His latest apperance was in Bowser's Dinner Date and Mario and Bowser's Stupid and Crazy Adventures.
