Here are some fun games our kids are now playing:

"Trade" (in which he gets her bottle, cup, spoon, toy, and vice versa)
"Tradeback" (allowed only if Mama is in especially good mood)
Grab Emi by the sleeve and tow her around the house (both giggling the whole way)
Tackle Emi, knock her down and sit on her (ditto)
Run up to cat and shriek at it in delight (Tuck only)
Give things to cat (Tuck only)
Point out eyes, nose and other salient features of cat (mostly Emi)
Try to move large objects, then comment, "Heavy, heavy" (Emi)
Move large objects (Tuck)
Wreck house -- oh wait, that's not a game, just their standard operating procedure.
