In a 1977 interview with The Lion and the Unicorn, Arnold Lobel said:
You know, if an adult has an unhappy love affair, he writes about it. He exorcises it out of himself, perhaps, by writing a novel about it. Well, if I have an unhappy love affair, I have to somehow use all that pain and suffering but turn it into a work for children.
It's straightforward to assume that Lobel's famous same-sex friends Frog and Toad drew, in a very general sense, from his experiences with emotional intimacy between men. But Adrianne Lobel and The New Yorker are happy to go much further and imply that Frog and Toad are gay-coded characters, even identifying the early stories as the beginning of her father's coming out.
Is there a strong case to be made for or against the claim that the famous amphibious friends are gay coded?
