Dororon Enma-kun Meeramera Temporada 1 Episódio 5

Whilst trying to find the Yokai Patrol concerning a case of bees causing people to become brainless, Harumi spots Enpi talking with the beehive demon behind it. Although Enma manages to outdo the demon, he and Kappaeru get distracted keeping a bee out of Yukikos yukata and get stung, reverting their brains to infant-like states. As Yukiko and Harumis attempts at taking over the main hero role fail, the demon challenges them to a series of events, promising to restore everyones brains if they win more than half of them. However, during one of the events, the demon ends up ticking off Enpi and gets beaten up, allowing Yukiko the chance to reverse the nature of Enmas flame stick and kill the demon. They later return everyones brains, only to get them mixed up.
