A few months ago, my FIL stopped by to pick up a drill. While chatting with dd#2, he picked up the drill and pretended to shoot her with it. Not to be out done, dd#2 picked up her favorite stuffed-up friend and shot my FIL.
To shoot a Manna-Gun, just lift the flipper, pull it down, and say, “Kapoosh!”
Now dd#3 likes to copy, but still do her own thing. She picked up her favorite stuffed-up friend and shot it, but in a different way.
To shoot a Cata-Gun, pick up the back end, lift the back leg, pull the leg down, and make a gassy “raspberry” sound.
This has got to be the father’s DNA.
