hello i am new on this forum but some may have seen me online on tsf

I have made 3 battle levels there but i am now trying to build a single player episode. I get stuck at some points so here are my questions.

1.
Is it possible to change (or add extra) boss music for boss fights? And is it possible to delte it that a music starts to play at a boss fight? (you must run over activate boss (becose it wont do anyting if you dont) but than the music starts to)

2.
How do you get something from a tileset into another? I realy dont understand how to make or edit tilesets. For example i want the sky of jungle into the tileset of carrottus. I am still a little n00by so if there is a way, please explaint it from the beginning.

3. How do you put in the tweedle boss (working). When i put him in he dont work (you dont see him and the boss energie is not show)

I sure have some more questions but forget them now

Btw, my english isnt very well becose i am dutch but i am sure you all know what i try to say right?
