Trapeetle

A Trapeetle is a spherical beetle enemy, with two large hands, swirly purple eyes and a spike on top. They appear exclusively in the Lost Kingdom of Super Mario Odyssey. Their name is a portmanteau of "trap" and "beetle". Upon the first time Mario tries to throw Cappy at the enemy, the Trapeetle will catch him in his hands to Cappy's surprise. After glowing red and charging up, the Trapeetle will launch Cappy back at wherever Mario is, which can cause damage if not avoided. Mario and Cappy can use this to their advantage, by luring the Trapeetle into throwing Cappy into destructible rocks, which can clear the paths or reveal hidden items inside.

The brochure for the kingdom warns heavily against them, referring to their explosive behavior as "a tragic display seen absolutely nowhere else in nature."
