Parakarry is Mario's fourth party member in Paper Mario. He is a Cyan Paratroopa and is the Mushroom Kingdom's primary mail carrier. In fact, at the beginning of the game, Parakarry delivers Princess Peach's party invitation to Mario and Luigi. It is this letter that starts the events of Paper Mario.
Parakarry works for the Post Office in Toad Town, the capital of the Mushroom Kingdom; his boss is the Postmaster. Parakarry tends to be quite clumsy and often loses the letters he is supposed to deliver, and it is also noted in-game that he is rather slow at delivering mail. As such, there are quite a few pieces of undelivered mail scattered across the kingdom. Parakarry's name is a portmanteau of "Paratroopa" (or perhaps the alternate "Parakoopa", as his name features a "K") and the word "carry", as he is a mail carrier whose ability involves carrying Mario.
In Paper Mario: The Thousand-Year Door, Yoshi has the same ability as Parakarry, to carry Mario over gaps that he can't jump over.
