Kookaburra sits on the old gum tree,
Merry merry king of the bush is he.
Laugh, Kookaburra, laugh, Kookaburra,
Gay your life must be!

Kookaburra sits on the old gum tree,
Eating all the gum drops he can see.
Stop Kookaburra, stop Kookaburra
Save some there for me!

Kookaburra sits on the old gum tree,
Counting all the monkeys he can see.
Laugh Kookaburra, laugh Kookaburra
That's not a monkey, that's me!
