Froggy the Gator and Mr. Hummus ride the bus to visit Mr. Hummus' grandad, Grandfather Hummus. What an awesome day for the two friends. But unsurprisingly, when they get on the bus, their imaginations start to take over. And before they know it, they're in a medieval forest! Then they encounter the fearsome medieval bandit Gershwin. Will they be able to best Gershwin in an the archery contest, so their bus can travel safely?
