The Second Wave Lalaloopsy Littles have been out at TRU for some time. Given the month or so gap between Lalaloopsy Little Wave 1's appearance at TRU and then at Target, I'd guess Wave 2 will show up at non-TRU locations in a few weeks to a month. I am fairly certain that TRU has some kind of limited-time exclusivity deal... like maybe they've made a deal with MGA so they exclusively have each wave of Lalaloopsy Littles for a month or so before other retailers can order them.

The Hartford area Targets are getting more and more of the Operetta wave. I hope they show up closer to you soon!
