In 1988 with the larger first series ghost figures and larger Gooper Ghosts already on the market Kenner created and sold smaller Mini ghosts. Which are different, separate, and more affordable ghost figure sets. At $4.99 USD, (1980s dollars, nice) even your allowance money made these obtainable toys.
Out of the three mini ghost toys I can remember having Mini Traps.™ Before I owned them again as a collector I vaguely remembered what they look liked, not really their purpose. I grew up in suburbia, grocery stores in practically every direction within a mile of me. If we had to set traps, it was to catch irritating bugs or on a rare occasion a mouse. Usually because of neighborhood construction. So I wouldn’t have totally understood how clever Kenner employees came up with mini traps. Cincinnati, Ohio must be close enough to the woods that perhaps there were traps made from iron to trap animals who can cause the outbreak or want to eat us. I’m not judging Kenner employees, they did what they had to, to survive on Kenner St.
