Rat boofies

mouse people watching the behemoths refer to them as "AAAAAAAAAAAAAAAA"

Alarming amount of Ratmongers being squished by the giants

they are dropping like flies in the great clasps (mousetraps) and fields of no return (glue trap)

A lot of creatures don't see them as a nuisance, sometimes they hire them to take out bugs in exchange for a home, and cheese

rats if they were actually cool instead of getting in my wall and scratching on the back of a light switch

Some of them are traveling merchants

ratmongers spending a whole fortnight trying to leave a neighborhood

They also make pretty good thieves

Yes

The Ratmongers strike

what will I ever do
