umbungo 

A 1980's fruit drink

Way down deep in the middle of the Congo, a hippo took an apricot, a
guava and a mango. He stuck it with the others, and he danced a dainty
tango.

The rhino said, "I know, we'll call it Um Bongo", Um Bongo, Um Bongo,
They drink it in the Congo.

The python picked the passion fruit, the marmoset the mandarin. The
parrot painted packets, that the whole caboodle landed in.

So when it comes to sun and fun and goodness in the jungle, They all
prefer the sunny funny one they call Um Bongo!
