Sorry it was too rushed especially when you have kids around and I didn’t take any pictures. Feel free to reformat or remove this post.
Apparently some Bunnings stores now have a “Find Rudolph” game in store, for kids only. They very likely to reject your participation if you are NOT accompany with a child.
You know if the game is available by going to Information desk and spot a Santa toy (~15cm tall) with a sign something like “Help me find Rudolph”.
A Rudolph figure/toy (~15cm tall) will be places randomly in the shop, you’ll know when you find it as it has a sign something like “I’m lost, help bring me back to Santa”. Take the toy back to information desk and let a staff know.
They’ll need to take a picture of the kid with Rudolph and Bunnings building block, likely for marketing purpose, and the toy is yours (Building block, not Rudolph)
These kinds of activities are run by individual stores. It is not brand wide. One store will be doing it and two hundred won’t be.
Thanks for clarification and setting correct expectations
