I love that Corban enjoys singing (Side note: He enjoys his singing and NOT mine. If I start singing it usually isn't long before he is saying "stop singing!" What do you do?)
So you will notice that this is a unique version or Popcorn Popping on the Apricot Tree. During the first line he changes his mind and starts immediately into the chant like song-about the monkeys and the alligator (reminds me of monkeys jumping on the bed but it is more exciting)
I will put the words so you can understand him better.
5 little monkeys swinging in tree/teasing Mr Alligator/can't catch me/you can't catch me/Along comes Mr Alligator quiet as can be/And SNAPS that monkey right out of that tree!
(Izzy loved this song! She laughs every time the snap comes)
