The revelation that Bulk's armour had a tardis-like effect was quite surprising. Though, it did answer some of the unimportant questions accumulating at the back of his mind. Did Bulk carry around supplies with him during his shift? If so, where did the larger Pegasus store them? He didn't have any pouches, pockets, or even fishnet to hook things onto on the outside of his armour. Given Bulk's overall size, it was also a snug fit to get into the metal armour in the first place.
