Round and round Academy Island

Ruby chased Kuriboh,

But Ruby thought 'twas all in fun

Pop! Goes Kuriboh.

A penny for his special effect

A penny for the Gem Beast,

That's the way our Ruby goes,

Pop! Goes Kuriboh.

A half a pound of ruby gems

A half a pound on his tail.

That's the way that Ruby's made,

Pop! Goes Kuriboh.

Up and down to Obelisk Blue

In and out of Slifer,

That's the way that duel spirits go,

Pop! Goes Kuriboh.

Juudai and Johan have found them now,

They have found them fighting,

They scold them quick and then they're gone,

Pop! Goes Kuriboh.
