"The Princess in Black is ready for her snowy playdate with the Goat Avenger and the Princess in Blankets. It's a perfect day to build snow monsters and battle them for practice. But just when they're about to wage battle, a huge foot smashes their snow monster. "SQUASHY!" It's a giant, and it's smashing everything in its path! The giant is too strong for the three friends, so the Princess in Blankets has an idea: it's time to light the Sparkle Signal and summon help."--
