Jude's Playground Adventure with a Mysterious Ninja and a Pet Dragon

A boy named Jude is often bullied by a kid at his school, who never shares and won't let him play. One day, during recess, a lightning bolt strikes the playground and a ninja appears, who is able to fit through a small window. The kids try to catch the ninja, but he outsmarts them and escapes. As they're leaving the school during an alarm, a red lightning bolt hits the bully and he disappears.
