May quickly introduced it to Pokémon Contests, where it adapted well. It was first used in the Battle Stage of the Saffron Contest, defeating Harley's Ariados, which was its first major accomplishment on May's team.
In Weekend Warrior, May was still deciding which Pokémon to use in the upcoming Silver Town Pokémon Contest. She sent out Squirtle, but she was not very satisfied with the way it came out of its Poké Ball as she needed its entrance to be flashier. Squirtle took May's comments to heart and disappeared from her sight for a little while, only to return using accessories made out of flowers in order to look more appealing and impress its Trainer.
May reassured Squirtle that it would always look cute in her eyes, and when the Silver Contest got underway, she used it in the Appeals Round. Squirtle began by using Ice Beam while spinning around and then proceeded to use Bubble, creating one large bubble surrounded by several smaller ones. After that, it jumped on the large bubble and used its Ice Beam to destroy the surrounding bubbles. It then used Ice Beam once more, this time aiming on the large bubble. The splash resulting from the explosion was frozen solid, creating several ice pillars and Squirtle finished by posing atop one of them. The performance impressed the judges and placed May among the four Coordinators moving on to the Contest Battles.
In Harley Rides Again, Squirtle was used in the first round of the Wisteria Contest. Its performance started with it using Rapid Spin to spin across the stage rapidly. It proceeded with a Bubble attack, making a spiral of bubbles while still spinning around. After that, it used its Ice Beam to destroy the bubbles and create a frozen fountain. It received positive reviews from allthreejudges, advancing May to the second round.
May's Squirtle is distinct from Ash's Squirtle, as it is much younger and smaller, mainly because it was intended to be a starter Pokémon. Squirtle started out relatively shy and was a bit of a crybaby. It has considerably grown since its first appearance, crying less and competing in more Contests. As a Wartortle, it showed a more boisterous attitude with no signs of the tears that defined it as a Squirtle.
