Plessie

Plessie is a orange dinosaur-like creature that will make its debut in Super Mario 3D World. Not much is known about it at this time, although it will first appear in World 1-4: Sea Serpent Ride, where Mario (and company) will ride it to the finish. It largely resembles Yoshi, and may even be a member of his species. It also resembles Dorrie, another dinosaur-like creature who the player rides through water in Super Mario 64, Super Mario 64 DS, and New Super Mario Bros..
