Clipless pedals on the kids trike??

Not really fast but not slow... I got out after dinner and found the large cear spot in the sky.. 30 miles and a good pace just a mile slower than I have had the past few rides. I want to make the strange creak noise go away it is driving me crazy. I might try to get some dirt this weekend that would be nice just means that I have to drive.. TGIF tomrrow is friday and that is badass..
