A-J's Quest

While listening in on evil prince Ostro's plans to take over the town of Beartown, A-J Bear and his pet hedgehog, Hedge, was captured and thrown into an abandoned warehouse.
Ostro has employed gigantic pretzels as minions in his campaign of conquest.
A-J must get out of the warehouse and find Ostro to save his home town. Ostro has frozen four of Beartown's princes into indestuctible force fields. You will need their crowns and any other crowns you can find to get through the doors to their domains.
Will A-J make it? Don't tune in next week, because only your skill, used right away, will give the world the answer.
You automatically use the most powerful weapon you have.
In order of strength {from weakest], they are: YO-YO, SWORD, SLINGSHOT, FRIZBEE. The last two weapons have a limited supply of ammunition and you need to get refills.
