Slug Around My Apartment and Seastar

The slugs' season is usually around the Spring time, but this one is still around in the Fall.
It is pretty big, but not as big as the one I can find around Deer Lake or Burnaby Lake.

My son loves sea stars, so I thought to just include this picture taken before he was born in 2006. 
Wow...it was 4 years ago?  Time passes too fast.  Where did the last 4 years go?

The slugs I saw around lakes before were huge, sometimes up to 20 centimetres.
