Rainbow Dash is Daring Do's official sidekick, which is the bestest thing to ever have happened in her life since she got allowed into the Wonderbolt's academy. Now helping one of the greatest heroes in the world, she finds herself enjoying life quite a bit.

Yet things are shaken up when the duo takes a small cube from Ahuizotl. Not only is this piece a key to a mysterious location called the sacred bell tower, but also has Ahuizotl somehow managed to steal it from Tartarus itself. Daring and Rainbow prepare a ritual to get it back there, and from there on out, everything will just go downhill.
