Book 1 Scooby-Doo and Snow Monster

I read "Scooby-Doo! and the Snow Monster"

Scooby, Shaggy, Fred, and Valma went skiing.
They stayed Big Pine Lodge.
There were owner, Mr. Squall,
and his granddaughter Cindy.
On the way to the lodge
they saw a strange thing.
It looked like a big man or a bear.

After snowstorming, they start to ski.
Then they saw the strange man again!
It was a snow monster!
Snow monster tried to catch Scooby and Shaggy.
They run away as fast as possible.

However, they noticed some things.
They followed monster's foot print.
Scooby found a red scarf.
It looked like Cam's.
Cam is the boyfriend of Cindy.

Cam wanted to stop business of the ladge
to protect their beautiful mountain.
So, he tried to oust them.
Cindy promised him not to sell their nature.
