Free ice cream at IKEA (at least at Lakeside) - Easter egg hunt

At IKEA, you can pick up an Easter egg hunt form at the entrance and the kids have to spot five different colour Easter eggs around the store. They are basically hanging signs in five different sections, like the image added. Once completed, take the form to the bistro bit, after the tills, and claim your free ice cream! This was at Lakeside but presume it's at all of them over Easter, Lakeside one ends 15 April.
