STORY: T and O run quickly so that they won't be late. P pops in and tags along with them. B, U, and S run too. S tells them to stop.
A bus appears, and T, O, and P steal the bus. S thinks...
S, U, and B hop in the sub, but it can't move. So they chase after the bus. Meanwhile on the bus, P pops downstairs and finds that there's no driver, and pops back up. S hops on the bus.
What will they do?
