I love your questions that come from translating Heavenletters into Dutch.
I think pollywogs are the same as tadpoles. Little babies who swim before they become toads.
Does that fit?
Emmy, if you include with your question a sentence or two the word appears in, that will give the context of the word as it is being used.
You are doing such a great job.
Thank you so much!
Love and blessings, Gloria
