Print adverts for Zoop give the pieces in the game their own names:

• The olive-shaped green piece is called "Ganggreenus"
• The martini-glass-shaped purple piece is called "Martinicocki"
• The boomerang-shaped blue piece is called "Infectococci"
• The baby's-dummy-shaped orange piece is called "Lockjawbacilli"
• The yellow splat-shaped piece, used as a power-up in the game, is called "Fungusamungus"
• A spiral-shaped piece, not present in the game but resembling the spring power-ups, is called "Mosquitick"

It should be noted that the splat and spring pieces are given different names in the game's manual: "Color Bomb" and "Bonus Spring" respectively.

The patterned square pieces from the Game Boy version of the game do not have names.
