Google “random stock photo” and find some unusual pictures to put around your room.
You could do “qu’est-ce qu’il y a sur la photo?” OR you could do the much “funner” 12 questions game

Pupils have to fill in 10 sentences about the picture and be as creative and funny as possible then as a class you vote on your favourites to create his “identity”
Il s’appelle …
Il a … ans
Il habite …
Il travaille comme …
Il aime manger …
Il aime jouer …
You can make the questions as easy or hard as you need to – some will need the sentence, some you could ask just the questions;
Comment s’appelle-t-il?
Quelle âge a-t-il?
