DonkeyBat

A man neglects his children and forgets the promise to take them to a kite festival in Spain. He spends all his time at work, ignoring his family and their dog. One day, the children go to the festival on their own. In a story he once told them, anyone who neglects their family turns into a donkeybat. The dad turns into one at work and flies to the festival, where he helps his children and turns back into a human.
