Update: Apparently these are available at the checkout lanes at Target stores. Either I haven’t been to Target enough or they just haven’t hit our area yet. I was there a couple nights ago and saw nothing but Mini Zane’s Ice Tank. Guess I’ll have to look closer next time.
Found at LEGOLAND California. $4.99 a pop. Polybags found at LEGOLAND typically show up or have shown up through other retail outlets. Like, they had the Green Dragon Mech polybag that was a Shop@Home promo and the Milano Spaceship one too. I haven’t seen this one elsewhere yet.
