In Pokémon: Magikarp Jump, Casteliacones can appear as food that can be consumed by Magikarp. They are unlocked at Trainer Rank 60 and cost 92,874 to unlock.
Casteliacones were first mentioned in A Venipede Stampede!. While being in Castelia City, Iris accidentally led the group to the stand selling the treat, where they found out that it was closed. The same stand was referred to again in Climbing the Tower of Success!, when Ash, his friends, and Stephan were trying to solve a quiz at the Wishing Bell Festival.

However, as soon as the ice cream had arrived, both it and the pie were eaten by Morpeko.
