I have finally figured out where Josh got Collowina from as a name for his non-existent second sister (see this post). He is (as well as I am) a big fan of the Froggy books by Jonathan London. Well, one of the books is Froggy’s Little Sisterwhere Froggy (you guessed it) gets a new little sister. Guess what her name is? WRONG! But close. It is Pollywogolina. Polly for short. That’s hard for a 31 year old to say, much less a four-year-old. So Josh paraphrased it to Collowina, like Froggy’s little sister. Kinda. I’m still not sure about Jam-og, but I’ll let you know how that goes. And that, my dear Watson, is elementary.
