Bluey: The Videogame

This one is gained in Episode 4 (Treasure) and is story related so can't be missed but there are collectables that can be missed. Tag grandad (Mort's) tail a few times when prompted to freeze and unfreeze him and achievement will pop.

This guide will walk you through this achievement and all of the other 21 achievements in under 2 hours. Freeze! achievement starts at around 1:04:03 into the video. All achievement timestamps are shown in the video Description.

You will get this achievement at the very beginning of episode 4 called 'Treasure'. The family will mention a game you used to play with the Xylophone and the story will tell you to test it out on Mort, and after the second time you freeze Mort this achievement will pop. It cant be missed.

If you need help you can follow my video which will begin at this point and guide you through it:
