With several Slowbro scouting around Cerise Island, Green covered Yellow, Bill and herself on her Jigglypuff with her Horsea's Smokescreen. so they wouldn't be found by them. When Yellow dropped the map about Cerise Island, it fell into the hands of one of the Slowbro. They hoped it would throw it away, but it ate it instead, to the shock of them. Green then had Horsea attach itself to the Slowbro's tail and leave droplets of ink behind it, so they could get inside the volcano.
