The toy bear first appears when a father accidentally shrinks his Lidl jumper in the washing machine and gives it to his daughter to wear with her teddy bear.
The toy is a mascot for the German discounter's new charitable initiative, which encourages shoppers to donate new or unwrapped gifts for less fortunate children in their local community.
Lidl said it is welcoming donations of all kinds and sizes, from small stocking fillers to sought-after items such as toys, games, books, puzzles and arts and crafts.
Lidl GB chief commercial officer Peter de Roos said: “Instead of selling Lidl Bear, we’re asking everyone who can to spare a bear, and other toys, to give to those in need this Christmas.
“From Kevin to Percy and everything in between, all toys will be welcomed with open arms – because there’s room for everyone at the table this Christmas.”
