It was a Slowbro holding a Leppa Berry, it was named Funbro. It knew Recycle, Heal Pulse, Block, and Slack Off. Basically Funbro would trap the opponent and just heal himself to PP stall the enemy. Once that's happened, he would Heal Pulse them to make sure they don't faint from Struggle recoil. He would throw in some Recycles to renew his Leppa Berry so he can continue healing and all that's left to do is wait for them to quit.
