Welcome to the Pokecommunity Magma Grunt! Just don't take away all out water and you should be fine :p
But in all seriousness, you can talk about yourself here for your introduction :) It can be as much or as little as you like ofc, like maybe just talk about things you like about Pokemon if you don't feel comfortable sharing who you are fully. There's no real wrong way to do it tbh haha. Also, if that was a serious question unrelated to Team Magma, I went and checked your profile and you're all good mi amigo.
Hope to see you around the forums, and have a splendid day!
