* Rampardos is a Rock-type Pokémon.
* Dim Sum is a style of Chinese cuisine.
Pokémon are not found in food, they are fictional creatures that live in the Pokémon world. You cannot capture Rampardos (or any other Pokémon) in real life.
Perhaps you were thinking of a Pokémon game? If you want to capture Rampardos in a Pokémon game, you'll need to find it in the wild, weaken it with attacks, and then throw a Poké Ball at it.
Could you please provide more information about what you're trying to do? I'd be happy to help you find the right information! 😊
