I’m looking for a toy for my little cousin’s birthday, and I don’t know what the term is for the genre I am looking for

I saw a review for a set of what the reviewer called “unboxing toys”, in which the process of opening the package to get to the toy is turned into a whole experience. The main focus of the video was a criticism of Beast Labs by comparing it to similar more fun products at lower price points. This genre of toy seemed really fun, like an escape room in a box. One that captured my attention was the Treasure X Dragons Realm Treasure Chest in which the kid must

1. unlock the chest with the skeleton key
2. excavate the three secret artifacts of power, discover the dragon armor, and find the three dragon riders
3. slot the artifacts into the treasure map
4. activate the secret switch in the eyesocket of the skull
5. unlock the secret compartment
6. unchain the dragon!

Obviously this could make for an epic experience, and I want to find more toys like this. Google says the word for this genre of toys is “surprise toys” but whenever I try to use that as a keyword I only find boring lootbox bullshit like LOL Suprise dolls and kinder eggs. How do I find more toys like these, which are more about crafting a little experience with a thematic puzzle?

Edit: Forgot to include a piece of important context. My little cousin is turning 3 on his next birthday and likes “dinotaurs” and “dagons” because they roar and smash things and eat his cars and trains. This gift is more for his dad than him, since the little cutie will need to be guided through the puzzle which will a good opportunity for quality time.
