Anyone know where I can buy Yo Gabba Gabba merch? (not online)?

I have looked at Toys R Us, Target and Wal Mart. I can't seem to find much at all. It's my sons favorite and we are trying to find toys to take on vacation with us and we don't have time to have them shipped. He's only 18 months so we'd take anything. Party supplies, coloring books, figurines...you name it and he'd love it. HELP!
