UP AND AT EM'! Peppino and Noise sprites ripped from @DocStoat Lore: An unknown figure has created a device that makes portals to different settings or universes, but he needed a place to house them, so he chose the well known pizza tower. He kicked out pizza face and took over, putting all the portals in the doorways of each level. That included boss levels, which Noise was kicked out of his domain, and became furious. He traveled to the famous Peppino Pizza to warn him about the tower above since he had nothing else to do.
