“Kosher” books for toddlers ?

My nephew is 2 and half, really sweet, social kid.

His parents are orthodox Jewish and pretty strict about some things. Please do not make judgements about this in the comments, as that is not useful.

I am looking to get him books from the library that will help his speech development and keep him entertained. His parents are (relative to their community) open minded in some ways, but they're super strict about kosher rules and don't want him to have books with non kosher animals in them. I would love for him to have more books with a plot he can relate to so he can more frequently hear words that will be useful to him. Like things around the house/foods, but with an actual plot.

He absolutely is obsessed with vehicles lately.

Looking for ideas for good stimulating books that could work, but have no images of animals (or only kosher animals like chickens, cows, ducks, goats, birds etc) I am aware this is not ideal. Would appreciate some genuine suggestions though!
