One day Pikachu and Jigglypuff saw a rainbow and they did not know what it was. They thought it was another Pokemon and they were scared so they ran away and Ash was looking for them. But he couldn't find them anywhere and he asked Misty to help him find Jigglypuff and Pikachu and he asked all the other Pokemon to help him also. He asked Brock and James and Jessie because they were nice today. The other Pokemon were naughty and they ran away too because they didn't want to be with Jessie and James because they didn't know that they were being nice today.

They ended up at the pool with Pikachu and Jigglypuff. Ash, Misty, and Brock, and James and Jessie looked everywhere for them but they couldn't find them. So they went and asked the nurse and she came and helped them too. But the nurse couldn't find them either. 

One of the sick Pokemon named Eevee told the nurse that they might be at the pool because that was their favorite place to go when they were scared. The nurse started to walk to the pool with Ash, Misty, Brock, and James and Jessie. 

Just then a blue hawk named Sandy and his wife named Watery were flying at Pikachu and Jigglypuff. The hawks almost got Pikachu and Jigglypuff. When Ash saw the hawks trying to get the Pokemon he ran to them with James and Jessie and the nurse with Eevee and Misty and Brock. Eevee jumped out of the nurse's hands and bit the hawks and they flew away. 

Pikachu and Jigglypuff thanked Eevee because she was so nice. They helped her swim in the pool and then she felt so much better. Then all the Pokemon went back to Ash and he told them never to run away again. And they didn't.
