Rappa Parappa and Hello Kitty

When I say boom boom boom you say bam bam bam
A Hello Kitty necklace is hangin' on my model, Sam

One of these is a dog and the other is a cat
Gutierrez made the patch and ~seel-dingo bought the hat

I got Parappa's hat right on the fourth try
And I finished Hello Kitty before half a day went by
