I got to the point where one lizard saves another and I don’t know where to go, tell me please, can I be stupid? (I used a translator because it's not my language, sorry)

I have found the stuffed animal and returned it to one of the lizards. Now I am wondering around the map not knowing what I am doing. In the process I have found (I think 3) question marks. What are they supposed to be? I have also found 5 blocks that wont let you pass to another section of world.....help?
