Although Jessie says Lickitung is one of her Pokemon the kid stole, she doesn't actually catch one until "Princess vs Princess."
Misty: I can't believe he took all my pokémon! Staryu, Starmie, Goldeen, and Horsea.
Ash: Misty, you forgot Psyduck!
Misty: Oh I wish I could forget Psyduck.
(The Pokéballs all let out voltorbs)
Jessie: That kid tricked us!
James: That two-timer!
Meowth: Yeah, he tricked us two times in one episode!
Who's That Pokémon: Farfetch'd
This episode was aired out of order in all countries, and technically takes place after "Princess vs. Princess".
According to some sources, the Farfetch'd trainer is named Keith. However, his name is unconfirmed in the episode. Because his dub name is unknown, this guide refers to him by his Japanese name.
Pokémon Debut: Farfetch'd
Title Pun: So Near, Yet So Far
In Japan there is a legend that if you are lost and starving in a forest, a duck with a leek will appear, and let you cook and eat it. This is why Farfetch'd carries a leek.
