Tiny, realistic puppy figurines the size of your thumb, each one a different breed with its own name and personality. Kids collected them, traded them, and spent every cent of allowance chasing the ones they didn't have. More than 140 breeds. The checklist never ended.
Galoob's inch-high robots, sold three to a pack and split into two warring camps: Z-Bots, Designed to Defend, against Voids, Made to Menace. A Micro Machines spin-off scaled down to the size of a thumbnail.
