Kryll heard what Rai had said and put it together.Seeing as how he didn't have to catch Hale anymore he quickly withdrew his tail before feeling for the vibrations on the ground.Being a snake had it's perks as he listened in.When he found where the Mew was he jumped as high as he could into the air using his tail for a spring before coming back down hard using poison tail where he thought the Mew was.He hoped that the impact would unearth it.He knew they should have ran,but maybe they could take the oppurtunity as he fought with the Mew.
