[TOMT][book] A French/English series of searching books, like I Spy, except cartoon

The books were soft-covered and about 20 pages long. Each page featured a clustered cartoon of chaos, like a monster's lair or Santa's factory. And along the left-hand side, there was a list of about 30 items to find. I seem to remember that bats, witches and brooms were common themes, but I may just have had a Halloween special. Definitely in French, 80% sure they came in English, too.

Possibly Scholastic?
