Piranharama Dennis & Gnasher : Season 2 Episode 17

Dennis and his faithful hound Gnasher are out to make every day as much fun as possible, but their adventures often lead them into trouble. Dennis decides to get a pet pal for Gnasher to keep him company while he's at school. After a few misfires, they find the perfect playmate: The Abyssinian Wire-Finned Piranha. However, they find out too late that there is only one condition - they must never, under any circumstances, feed it pies... Uh-oh. What's the worst that could happen? Surely not a flatulence-induced tidal-wave of destruction?
