Trip's Vanillite was first seen battling a wild
Palpitoad. It used
Ice Beam on its feet so it couldn't escape.
Trip tried to catch it with a monster ball, but
Ash Ketchum got hit by it instead.
Just before
Ash Ketchum and
Trip's three-on-three battle,
Iris encountered
Trip's Vanillite. She instantly tried to avoid it and started to shiver. She explained that since Dragon types have a disadvantage against Ice types, she dislike the cold that Ice Pokémon create.
Trip tried to confront her about her dislike of Ice Pokémon by telling her that Dragon Pokémon are also strong against Dragon Pokémon but she only reluctantly apologized to
Trip's Vanillite and her mind wasn't truly changed.
Three-on-Three Battle Against Ash's Tepig
Ash's Tepig was sent out and
Trip's Vanillite was sent out to battle it.
Trip's Vanillite had a major disadvantage against a Fire type like
Ash's Tepig but
Trip had intentionally paired them up because he wanted to win against
Ash Ketchum by using his nonsensical battling style.
Trip's Vanillite proved to have high defense as it was able to endure a direct
Ember attack. It then countered with
while Ash's Tepig used
Flame Charge but they both ended up knocking each other out leaving the battle at a draw.
