Flip Flap

Urban-dwellers seeking to balance the person-to-tree ratio will find a friend in Flip Flap, a petite plant that looks and moves like a cartoon. Waterless, batteryless, and sunless, it's waving leaves may be the lowest cuteness-to-maintainance ratio out there, but you're not completely off the hook – the packaging requests you "please grow your Flip Flap in your mind and bloom your own special flower."
Available at Compact-Impact for $32.
