My Little Pony: Friendship Is Magic - 2x07 - May The Best Pet Win!

    After discovering that the other ponies have a pet play-date each week, Rainbow Dash decides that she should have a pet.  Fluttershy offers her a variety of choices.  Rainbow wants something that emulates her - she wants it to be a very fast flying, agile, cool, clever creature.
    So they go through a variety of tests to see which animal meets her criteria.  The last one is a race through a canyon.
    When Rainbow is caught in an avalanche, all of the other animals are well ahead.  She's trapped, with one of her wings pinned under a boulder.  Eventually, the pet she had ruled out, a tortoise, arrives, and helps her get out.  They cross the finish line together, and she names the tortoise Tank.
    It's a fun episode.  There are plenty of good sound effects, lots of interesting things to animate.  But there isn't as much with the other main characters.  This can be a little disappointing, since it's so fun to see Applejack throwing a stick for her dog, or Gummy the alligator latching onto Pinkie Pie in different locations.
