Apples writes in to say that the LEGO Ninjago polybag set Skeleton Chopper (30081) has made an appearance at ToysRUs in the US. If you recall back to the beginning of February, Brickset discovered four of these Ninjago promotional sets. I believe Target and ToysRUs have been the only stores to feature these Ninjago polybags, to date.
Apples also noted that the Cole DX spinners were in store as well, so it may only be a matter of time before all the new spinner sets are in.
