many things is different from the games.
-pp doesn't exist*
-aqua ring protects user from electric attacks
-eggs have same colors as the Pokemon
- Pokemons can have more moves than 5
the anime would lose its points if everything was just like the games. thats why its often added a little spice to the anime, like 5 moves on snorlax. you just have to accept it
hope I helped :)
*well, no one have ever mentioned it
