Just to correct my previous blog - a group of penguins is not called a pickupa of penguins. I have just learned that the name for a group of penguins changes by location. The all encompassing term is a colony, a group of nesting penguins is a rookery, and a group of penguins on land are called a waddle.
I like waddle of penguins but if we all call them a pickupa of penguins and teach this to our children can we create a new word? Try, I´m going to.
