Here's why:
* Mega Punch is a fighting-type move: This move is designed for attacking Pokemon, not interacting with the environment.
* Trees are not Pokemon: Trees in the game are part of the scenery and cannot be attacked.
To interact with trees in Pokemon Shiny Gold, you need to use the following:
* Cut: This HM (Hidden Machine) allows you to cut down trees that are blocking your path.
* Berry Trees: You can shake berry trees to collect berries, which are a valuable resource for healing and battling.
Remember, always check your Pokemon's move list and the specific interactions allowed within the game to see what you can use on each object.
