Glohbb

The 'Glohbb was creature from another dimension that was able to instill its mind into any big gooey form. A failed invasion involved the distribution of free buble-gum dispensers on street coners. Once discarded it developed a collective consciousness and the smaller pieces made their way to join with other pieces in much the same way as cells behave. It's size continued to grow untill finally the link between dimensions was broken by the intervention of the Doctor who used and oxygen cyclinder in order to blow the gum apart. (COMIC: Gumfight)
