As Legerd says above, Snowbird could take the form of Sasquatch, due to him being a combo form of Walter and Tanaraq (born/created in Canada)...And yes, Snowbird taking the form of dead Beasts is a retcon...Since she shouldn't technically be able to take on the form of Neootoq (unless that form was somehow created on Canadian soil).
