Sgt. Frog Season 5 Episode 236 Keroro: Wanna Chew Some Gum, Sir? / Tamama: Tamama Tango, Sir!

The new Pekoponian invasion plan calls for mass distribution of Kululu-created bubble gum that causes various annoying effects like weightlessness and the compulsion to litter (and then step on it). Later on, after the platoon gathers mushrooms, a witch hunt ensues to find the Keronian who ate a poisonous mushroom that will turn him into a contagious Mushroom Man.
