There's A Storm Brewing

As they emerge above ground, our heroes bounce their way up the giant tree again only to encounter the nasty Meowth stuck on a branch! After wacky encounters with a Gyarados and a Snorlax the gang gathers together on a high branch in the tree. Just then, the sunny sky begins to darken, sinister clouds appear and the wind start howling, sending all of the Pokemon running for shelter.
