The very puzzling caterpillar

As I wrote before, I often read English books in Russian for Sasha. It is very interesting to see his reaction to certain books. There are sometimes pages that puzzle him, and he keeps returning to those again and again. For example in Tubby Time by Leslie Patricelli, Sasha always pauses on the page where the baby got soap in her eyes. He keeps pointing at it and asking something in his own language, and my only guess is that he thinks that the baby is crying and he wants to know why. And I cannot find the right way to explain to him that the baby got soap in her eyes.

And so is the case for The Very Hungry Caterpillar by Eric Carle. Sasha keeps turning to the page where the caterpillar is extra fat, right before it turns into a cocoon.

I keep going through the book and explaining that the caterpillar ate through everything and turned into a cocoon to eventually become a butterfly, but Sasha seems confused... Until one day he just pats on the brown cocoon and says: "Kaka, kaka i pakaka", which sounds exactly like my expression: "Какал, какал и покакал!" (Pooped, pooped, and pooped it all out!).

It may be funny to you, but this is the most logical explanation to the child who is often constipated after his parents feed him all kinds of stuff. It definitely makes more sense than some cocoon. And hey, at least, Sasha does not think that the caterpillar is a "wasteful capitalist"!
