snow pants and sleds

My pants say:
“vvvvvt-vvvvvvt-vvvvvvt-vvvvvvt”
when I walk in the snow.

The sled goes:
“ssssssssh-ssssssssh-sssssssh”
when I go down the hill.

The watching crow says:
“Caw! Caw!”
from a tree-branch.

My brother’s leg goes:
“SNAP!”
when he catches the snow wrong.

He cries, and we go home.
