i don't know where to get blabla dolls, but my baby loves these finger puppets i got at ikea. to clean, i just throw them in with her laundry using a garment bag so they don't get lost.
i just bought 2 at smarty pants on Lyndhurst terrace (flat 1D, No. 52-60) i saw the ad on dollarsaver. there wasn't much left though. here's their tel. 25442700
