Bulstrode is a highly disagreeable barge.
Bulstrode was used to carry cargo like stone, but always complained about not being loaded fast enough. This annoyed the trucks. One day, Bulstrode ended up getting what he deserved when Percy accidentally pushed some trucks off the quay and into his hull. He was then towed to a beach, where he was turned into a playground. He is remains there today.
Bulstrode is bad-tempered and constantly complains. This coused him to be placed on a beach for children to climb on.
