Numb numb nom on this
Milk for your chocolate chips
Jumping on my pogo stick
Bags of candy make me sick

In this jungle gym I live
Girls and boys play like this
Fun is for everyone
Fun fun fun fun

This made me smile.

I particulaly like the deep metaphorical commentary on the political tension between India and Pakistan in that first stanza, higher order intelligence sir.
Music is an art form that celebrates potential. So long as you're looking for it, you'll always find it.

How about "Fun for everybody is" to keep with your pointlessly inverted word order in line five? Alternately, "I live in this jungle gym" keeps the facile rhyme scheme intact without injecting the pointlessly inverted word order.

Nothing to see here. Move along.
