Make "The Veldt" jungle theme play everywhere on the overworld Map.

Shouldn't this be a simple pointer change?

I thought of this quickly and tbh, I just assume my solution would leave open the possibility to use the overwold theme for something else.

A pointer change is in fact a simpler solution for someone who never coded. You could also opt for a solution similar to mine, but with an optimized approach. I'm sure there's a more elegant to do this than my coding.
