As our heroes enter Terminus Cave, Squishy takes off! Before the others can catch up, Squishy sends a message to a similar-looking Pokemon. This alerts Team Flare, and they scatter to catch Squishy (which they call Z1) and its friend, Z2! As Team Flare closes in, Squishy summons many Cells and merges with them to become a fierce four-legged Pokemon. It hits Team Flare with a devastating attack—and when that’s not enough, Ash sends out his Greninja, and the two of them appear to battle as one being! Team Flare finally retreats, but Squishy is missing. Our heroes set off to find it...as Team Flare watches their every move! (thetvdb.com)
