The yellow creature is called a minion(from the movie 'Despicable Me'). If you already knew that, I could give another hint.
After trying the proper way, unaided, for a long time, I succumbed to the image search that was suggested. It looks like a minion called dave, only with more hair. I don't know a used called hairy dave or anything remotely similar, so I'm still as clueless as a Norwegian during a cricket match.
