I've recently discovered that no one knows this song so i listened to it and found the 
notes on the guitar.
*Tree Hugger*
This is just the chorus but it's pretty much the same throughout.

    G
And in the sea ther is a fish,
  C
A fish thathas a secret wish
  D
A wish to be a big cactus
       G
with a pink flower on it.
 I'm livin with a friend who's really drama-y so i get bored and annoyed. So ive decided 
share this song with you ! it's my first tab so sorry if it's rough.':)
