Quiet as a mouse.
Like a bump on a log.
Does not make noise.
I'm a bear
The snow covers everything.
Big as a giant
The students are shining stars
The snow is a white blanket
Not active.
Great swimmer.
Sleeping like a log
Fight like cats and dogs
Sleeping soundly
Swims like a fish.
Do not get along very well
The students are very bright/smart.
Very tall
I'm not very friendly.
