Now I Bring You A Song

I'm trying to write a song to the tune of Old Mcdonald Had A Farm but I've only done a couple of lines, does anyone know what I could put next? Here it is:
Miss Bloatcheeks said one day, "ey ore ey ore oh"
Ben done a bloat bloat there, Barry clucked clucked there, bloat bloat, cluck cluck,
nostrils enlarging everywhere.
Miss Bloatcheeks squawked one day, and Barry and Ben joined in.
That's all I've got so far because I'm a sour faced trout. Like Ingrid.
Please comment if you have a line to add to it.
I am now lifting the left part of my top lip in disgust.

Ben

This gossip is delivered by my ahem resourcful sauces, this time it's the ketchup. This gossip is all about my brother Mr Ben or as I now like to call him, Squuuuuuuuuuaaaaaaaaaaaawwwwkkk. After the noise he makes after getting a letter from his pen pal. Theres your first bit of gossip. Ben says he has an idea: *bloats his cheeks* How nice for you Ben, I don't think David Cameron would allow that though somehow. Do you have another idea? *bloats again* ANY MORE??!! Ben says: Bloat your cheeks, and do your snubble expression at the same time, It has funny results. This blog has limited subjects, dosen't it? So you know what Ben means, my Snubble expression is above. It's....um...hard not to notice. Ben's going to tuck his paws under now.
