When I saw this was Papa Bear's adventure, and the description said something about "a base under the s...", I had to look. When I found out the s was "sea", I was terribly disappointed.
A big part of me was hoping it would be "spooky old tree."
lol don't count that idea out for the future. In fact... under a spooky old tree and family fun are ideas that might have already been on my mind
