I’m looking for a picture book about a teddy bear named “Jacques” that falls out of a boat into the ocean along with some other stuffed animals (a white sheep?). He sees mermaids and an octopus squirts him with ink. He eats “fish fingers”. It’s most likely English and I had it when I was about 4 or 5 back in ’89 or there about. The book had very interesting full page illustrations.
It’s been bothering my sisters and me for decades!
