I haven't been to this store in, geez, maybe 4 years, but if I remember correctly, the last time I was here they had puffers...

Are you familiar w/ the Cambridge area? If you know where Lechmere station is, and Twin City Plaza... you drive up away from Lechmere towards Twin City Plaza, and on the right side, across from the McDonald's, it's right there, next to the packy and Work N' Gear stores.
They have a ton of different fish and animals in there... when I was there they had a chicken running around. They bought him to feed to one of their snakes, but the guy who received the order liked the chicken so much they decided to keep him!!
