The Jetsons had Rosie. Luke Skywalker had C-3PO and R2-D2.

Clearly any space explorer worth his weight in moon rocks needs a sidekick.

For your little astronaut there’s Roboplush from Munaluna. Created by San Francisco textile designer Meredith Cheng, the Roboplush combines space-age good looks (rectangular heads and square bodies) with the cuddle factor of stuffed animals (irresistibly squeezable).

Crafted from soft, vintage-looking fabrics (yes, real robots do wear pastels), the toys have button eyes that are downright soulful (Cheng carefully reinforces them so they won’t come off). Far from cold androids, these softies are designed and weighted to feel like little humanoids when held in the arms of their small masters.

In other words, they’re out of this world.

Available at Cherish, 115 Clement Street, between 2nd and 3rd Avenues (415-379-7300 or shopcherish.com); online at munaluna.com, $36.
