In undertale Napstablook shows you his snail farm. He invites you to race a few of his snails. You have to press z to encourage your snail to make it go faster. Unfortunately as you press z the snail catches fire. You encouraged it too much and it couldn't handle the pressure. So be sure to take 10 minutes or more in your day to relax. Or you will burst into flames. Not really that won't happen.....
