One day, after having a diaper accident, Parker decided to attempt a self change. He went into his room, slipped off his dirty pelenka and threw it in the diaper bin, then laid out a changing mat. He got out a disposable diaper and laid it out on the mat before sitting down on it. He then laid on his back and folded the diaper over his groin. And after much struggle, he managed to strap the sides down. He stood up to admire his triumph, but as he did, he realized something. He put it on backwards. The tail hole was in the front and his tail was above the front part. Parker sighed as he took it off and let the machine change him.
