Not quite right

I'm in the process of making kid #2's first birthday invitations. I've done a few mock ups and nothing seems right. I've got my cute little jungly themed stamps, I have some awesome ribbon, I've got the plan for the card, but I can't get the colours to go. I can't decide on the colour of the card itself, and anything else. I'm trying to match it to the ribbon, which has a lovely light orange, green and a darker orange. I've tried Yellows, Oranges, Reds, Greens, Blues and nothing seems to go. I may have to hunt for some new ribbon.

ETA: Here are all the elements I've got and the little mock up that I've done (excuse the crap colouring job and any other parts that look rough, it is just a mock up afterall :))

I'm also horrible at coming up with a little verse to put on the inside of the card. The only one I can come up with is unbelievably similar to the card I did for Kid #1's birthday two years ago. I can use it, but I wanted something a little more unique. So if anyone can come up with something that rhymes with One other than Fun, and incoroporates Lions, Giraffes, Monkey's and Elephants I'm all ears :)
