There was a Unicorn bus, it can fly, turn invisible and move by itself. One day, there was heavy rain, the Unicorn bus broke down. The passengers called the mechanic immediately. The mechanic found out there was a small hole in the oil tank. But the mechanic said that he never saw anything like this but he said they can use solar panel instead, that way, it’s more eco-friendly and wouldn’t need to get gas which is harmful for our planet. All of the passengers thought this was wonderful idea. From that day on passengers did not worry about running out of gas.
