Oh! I just thought of one! Now some might consider it twaddle but it’s a fun book with a leopard, a monkey, an elephant, hippo, rhino, lion, and a turtle. “You Look Ridiculous Said the Rhinoceros to the Hippopotamus “. It’s out of print but you can probably find a used copy online or at the library. My kids roar with laughter every time they read it.
Can You Hear It? By William Lach has classic paintings matched with music. There are a few animal paintings in there, including one of an elephant. Carnival of the Animals is similar. It’s by Jack Prelutsky and Mary GrandPré. There are lions, elephants, swans, turtles, and kangaroos.
Edit– one more and I’ll hush. The Christian Liberty Nature Reader Book K has more zoo animals than the others in the series. It’s more factual but maybe pair it with poetry or one of the music books I mentioned?
