Wubbzy drops Daizy's sparkle stone ring into a hole, leading him, Widget, and Walden to the center of the earth to find the ring!
Daizy entrusts her sparkle stone ring to Wubbzy while she is gardening. Wubbzy, being who he is, drops the ring into a hole in the ground. This sends him, Widget, and Walden on a "Journey to the Center of the Earth"-like trek to find it.
Finally, they find the ring in a pile of marshmallowy goop. They give the ring back to Daizy. Daizy thanks Wubbzy and takes a lick out of the sparkle stone ring pop. She says that it's Grapety Grape, her favorite flavor. Wubbzy realizes that the sparkle stone wasn't so important after all.
