Elmo Kindness 1: Puppies.

Elmo imagines himself and his stuffed hamster, Henrietta, aboard the spaceship Kindness-1, roaming the cosmos to do kind deeds. They discover an asteroid field, plastered with lost dog fliers from an alien monster on the Planet 5, who has lost her dog X-Q-17-▲-Bloop (or "Wiggles" for short). With some navigation from computer program Blinky, they arrive at a distant planet and find Wiggles hiding among the craters. They return Wiggles to its owner. With kindness accomplished, home to Elmo's room on Sesame Street.
