S1·E146 Wanival and Dekanuchan's Great Sleep Operation!

Just as Wanival and Dekanuchan are suffering from sleep deprivation, Liko and the others run into Professor Neroli, a researcher of Pokémon sleeping. They all travel together to Wakakusa Island to try using the power of the Kabigon there to put Wanival and Dekanuchan to sleep, but the hungry Kabigon ends up waking up... and the group starts working on trying to make Comatose Butter Curry in order to fill it up and make it go back to sleep!!
