In Hunting the Nightmare, the egg hatched into Lickitung. It licked Rosa to identify her through taste, the resulting screams leading Voss and his poachers to them. When the Golbat attacked, Lickitung defended Rosa with powerful attacks, defeating the entire swarm.
In The Pokémon Ranch, Lickitung appeared on Hayley's Ranch. It enthusiastically licked Ursula, disgusting her by the saliva. It gave the same treatment to Rosa upon seeing her, excited to see her again.
In Collision with the Enemy, Rosa chooses Lickitung to battle Kodai's Shuppet, but it is Disabled from attacking. It is then restrained along with everyone else.
