Why doesn't this yarn want to cooperate?

Sometimes while creating objects with crochet, my yarn rebels against me. I was working on squares for a new "bright colors" afghan the local crochet group is coordinating. The first 2 squares cooperated lovely as seen below.

And then there was a third who obviously does not want to become part of this effort. After 2 rip outs, soon to be a 3rd I still can't get it to look right.
Wait, this is supposed to be my relaxing time and square #3 you are causing stress. I will figure out what to do with you later and oh yes you will be a square and a good square at that. Are you reading this bright colored acrylic yarn?
