Ash's newly caught Treecko may be a bit standoff-ish, but the little green Pokémon is quite a fighter. When Team Rocket sees Treecko knocked down and hurt by a Seviper, they decide that they must have that Seviper. Jessie is very impressed with its "sneaky, snakey ways." Meanwhile, Treecko escapes from the Pokémon Center where Ash brought it to recover. When the gang finds Treecko, it is practicing its attack moves. Again and again, Treecko jumps from the top of a waterfall and tries to break a rock at the bottom with its tail. Ash is very impressed with the rigor of its training. All of Treecko's hard work appears to have paid off—when Team Rocket attacks and catches Pikachu with the help of their new Seviper, Treecko is able to save the day.
The Who's that Pokémon? of this episode is Gligar.
