Jessie's Lickitung (Japanese: ムサシのベロリンガMusashi's Beroringa) was the second PokémonJessie appears with in Kanto; Jessie captured Lickitung in a fit of rage after it ate all her food and temporarily paralyzed her Arbok. Lickitung was the first Pokémon Jessie was shown to catch, and is the first Pokémon to have been caught by Team Rocket in the anime.
Jessie is unaware that her Lickitung has been traded to Benny
Lickitung was first mentioned by Jessie in So Near, Yet So Farfetch'd; however, she did not use it for another three episodes where it first appeared and had its most central role in Princess vs. Princess (the episode in which Jessie caught it was originally scheduled to appear before So Near, Yet So Farfetch'd). Lickitung was Jessie's forgotten weapon in the finals of the Queen of the Princesses contest against Misty. After stunningly defeating a borrowed Pikachu, Bulbasaur and Vulpix with its effective Lick, Lickitung was defeated by Psyduck after ignoring Jessie's 'Tackle' command, ending Jessie's run in the contest.
Jessie used Lickitung rather sparingly for the rest of its time under her possession, making the pink Pokémon her second option, after Arbok. Thus, it was one of the least used Pokémon that was owned by a main character. It most often appeared alongside Arbok, Weezing and Victreebel when Jessie and James used all four of their Pokémon in battle.
Lickitung, much like James's Victreebel, showed its affection for its Trainer rather openly. Lickitung licked Jessie's face on several occasions, but not nearly as many times as the running gag of Victreebel latching onto James' head.
In Tricks of the Trade, Lickitung was accidentally traded by Jessie to a Trainer named Benny for his Wobbuffet during a commotion at the Pokémon Swap Meet. As Team Rocket's scheme to steal Pokémon with a rigged trading device is discovered by the crowd, Lickitung's Poké Ball was dropped into the trading machine when Jessie was knocked backwards by Magikarp salesman who was escaping James, and is swapped with Benny's Poké Ball already in the machine; the person Benny had been planning to trade with had changed his mind at the last minute. Jessie soon realized the trade when she sent Lickitung out to battle Ash, and the passive Wobbuffet emerged instead.
Lickitung was seen living happily with Benny towards the end of this episode, and Benny tells Ash and friends to "thank the lady who traded him Lickitung". However, there is no indication that Ash and his friends ever identified the Lickitung as Jessie's old Pokémon, nor that Jessie's new Wobbuffet was originally Benny's. Lickitung and Benny have not been seen since in the anime.
