When grouped together which of these animals is the odd one out?
MOOSE MOUSE SHEEP DEER
Mouse the names of the others others are both the plural and the singular noun
"Mouse" is a rodent. The other 3 are ungulates.
If each one is in a group of it's own kind can you obtain a different reason?
@Polemicist "Mouse". The other 3 have 2 vowels in a row. Mouse does not.
