On a scooter there is a bear with a drop on its head trying to follow and chase you! You accidentally splashed it with water and it's not happy about it. You're on your own scooter, luckily, but that doesn't make this any less terrifying.
The bear is trying to follow you because it wants your obi (お) as compensation for its injured pride. The obi is waving in the wind behind your scooter, and the bear is reaching out with its teeth to try and grab it.
