Chinchou was used in the third round of the Whirl Cup. It battled against Misty and her Corsola. Chinchou started off by using Spark towards the sky and the electricity went straight towards Corsola. Even though the latter used Mirror Coat to defend, it still take damage. When Chinchou used Confuse Ray and Corsola dive underwater to avoid it, the former turn things around by using the attack again underwater and confusing the latter. Using Water Gun, Chinchou was able to knock out Corsola and win the match for Trinity.
