Mandmsarecol here! Sorry for the delay on this! I was busy again… 🙄 But anyways, here are all of the catolouge cheats!
The divers helmet in the clothing catolouge appears when you click on the paper hat, the viking helmet appears when you click between the trendy sunglasses and the floppy hat (same rules apply to getting the blue helmet as always) and the headphones appear when you click on the top of the festive sombrero. If you want the snowglobe igloo you need to click on every word “snow” in the whole upgrade catolouge and click on the basic igloo’s window in the catolouge. If you click the blue dimond in the blue dimond lenolium you get the secret stone igloo and if you click between the door and the window closest to the right in the ice castle you get the secret stone deluxe igloo.
