All of the Wurmple evolved into Cascoon while battling Taillow in an attempt to defend itself.
During a rainstorm Goh's Golurk unitentionally created, all the Cascoon evolved into Dustox in spite of the chaos around them under the protection of all their friends in the area, dispelling the rainstorm with Sunny Day and saving the day.
- They are Goh's first Pokemon to fully evolve.
- Suprisingly, the episodes they evolved in are prime numbers.
- These 3 Dustox are the second group of multiple Pokémon of the same species to be owned by a main character. The first is Ash's 30 Tauros, caught over 1,000 episodes prior.
