If HOSTESS & PETCO merged and became a medical supply company, they would sell ___

STETHOSCOPES

Think of what a vet might use to listen to a Twinkie’s heartbeat.

This clue plays on the names of two companies—Hostess (known for baked goods like Twinkies) and Petco (a pet supply store)—by pretending they merged into a medical supply business. The word "stethoscopes" blends "Hostess" (the start) and "Petco" (the end) while also being a real medical tool. It’s a pun that relies on the sounds of the brand names to create a funny, fictional product.
