The "Fantastic Pets Wings DLC Pack" has been released today. The DLC for Fantastic Pets
adds ten additional achievements worth a total of 235G.
The exact contents of the pack are a bit of a mystery, as THQ and Blitz Games are yet to issue a press release. The Overview on the Xbox LIVE Marketplace is just as helpful: "Please download this content".
Looking at the new achievements, the pack appears to add more customisation options for your pets, including colours and costumes. There also seems to be a new "Take Off!" activity.
The "Fantastic Pets Wings DLC Pack" costs 240 MSP and can be downloaded from here
