It's Halloween, and Goodly, Lovely, Angel, Neatly, and Perfect are planning the spookiest haunted igloo ever! They've decorated with spoohooky cobwebs, they've baked some awful waffle treats, and the only thing left to do is dress up as something scary to haunt the igloo. Everything is going spooktacularly . . . until ghostly hunters show up! They want all the penguins' snacks, but their trick-or-treaters (and, of course, snacky Tacky) have eaten them all. How will the penguins get out of this mess? Tacky will teach these trick-or-treating hunters that, if they can't get treats, they're surely going to get tricked.
