Sticky Situation Achievement in Bluey: The Videogame

The stickers are the collectibles across the top and the bottom of the sticker book. The newspapers, cakes, leaves, and cricket bats aren't needed for this achievement. 

The top section of stickers is easy. Just walk around each location and look for the telltale sparkle of a collectible. 

The bottom section is all plants, and to get these added to your sticker book, you need to fully grow each one someone in a location. For example, head to the outside area of the house, and you can find a watering can in the backyard. Fill it with water at a spigot, then use it to water one of the plants around the perimeter of the house or yard. Once the plant is fully ground, it'll be added to your sticker book. You need to do this with all unique plants in the game. This is harder to track because you can't look at an ungrown plant and know if you've collected that one or not. Well, not unless you memorize what the plants look like. So, just head to each location, spawn your watering can at a toy bucket, and use it to water plants in the area to add them to your sticker book.

If you're missing anything, refer to the following video from Sodaski that shows the locations of all stickers.
