I have built a treehouse 

 I have built a treehouse 

 Nobody can see us 

 it's a you and me house 

 I've been climbing rocks and stones 

 been collecting broken bones 

 I've been swimming across the lakes 

 just to find this perfect place 

 I got lost into the woods 

 I've been covered up in mud 

 I've been going through a lot 

 just to find this perfect spot
