Sammy the Sloth is visiting Diego at the Animal Rescue Center when a call for help comes in. A muddy mud slide is heading towards Mommy and Baby Sloth's tree -- and sloths are so slow, they'll never get out of the way in time! Sammy joins Diego on the rescue mission, where they tiptoe slowly to get past the harpy eagles, then sing 'sube' to help Linda the Llama climb up a mountain. Using his Spotting Scope, Diego finds Mommy and Baby Sloth at the bottom of the mud slide. With Sammy on his back, Diego rides his mud board down the mud slide and helps Mommy and Baby Sloth get into a safe new tree!
