Charlie Sheen -- G-Rated Time with the Kids

Charlie Sheen is downright suburban these days ... spending his downtime with the twins.


Charlie and the kids went out on a friend's yacht a few days back for some whale and dolphin watching off the L.A. coast ... and whaddya know?  We got the pic.

Turns out ... Charlie sees the twins often.

The kids even found treasure ... in the form of the gold tooth in Charlie's mouth. Ahoy!
