If you plan to attend Winterlude, they also sell some of the souvenirs at the Winterlude festival, so you might be able to find the plush toy there as well.
Next to the 2010 Ice Hog plush toy is the plush toy from 1994 (with the light blue and pink shirt). This one is no longer available. I found it second hand at a thrift store a couple of years ago and was quite happy about that! This 1994 plush toy was sold the same year that the "new and improved" Ice Hog mascots were unveiled. From 1980 through to 1993 the Ice Hog mascot looked very different....
I'm looking for the 1980's Ice Hog!
If anyone out there has an original Ice Hog plush toy from the 1980s and would be willing to part with it, please contact me! I would be happy to buy it from you (if the price is right). I recall the 1980s Ice Hog plush toy was wearing a blue hat with a white pom pom. It may also have a blue scarf, but I'm not certain. If you have one to sell please e-mail me: info"at"artellepuppets.ca
UPDATE JULY 2022!!! I found one!...
