Pokémon : S5 | E40 – I Politoed Ya So!

Ash and his friends pause for a picnic by a lake, and call out all of their Pokémon for lunch prepared by Brock. Ash compliments Brock on the food, a sentiment shared by Pikachu and all of the Pokémon, to which Brock emotionally plies everyone with more food. Cyndaquil scoffs down two rice balls at once and begins to choke. Ash runs over to help, and a small pat on the back causes Cyndaquil to use Flamethrower to clear its airways and roasts Ash's face in the process. After lunch, everyone has a nap, except for Misty's Politoed, who decides to have another rice ball. In the process of taking one, it knocks the food off the plate and it rolls into the bushes.

Politoed chases after its snack only to be discovered by Tammy, who admonishes "Bean" for running away and losing its red headband again. Resigned to Politoed's behavior she takes its hand and starts walking home, just as another Politoed wearing a red headband wanders out and watches them, seemingly confused. Tammy returns to a large building and announces to a group of Grass-type Pokémon that she has found Bean. However, the Sunflora, Jumpluff, and Bellossom all crowd around, confused, and the girl realizes that this Politoed is not her own. Politoed promptly begins clapping happily, and the Grass Pokémon all enthusiastically dance and sing to the rhythm. Astonished but happy, Tammy exclaims that she loves Politoed.
