Penguin from an Ice Cream

A long time ago, a little girl was on holiday with her family. They sat down to have afternoon tea at a café. 

As children are wont to do (and get away with while on holiday), the girl asked for ice cream. 

You can imagine her delight when the ice cream arrived, with this little penguin perched on top. 

At first thinking it was edible and wondering how she would ever be able to eat such a delight, she was very happy to realise it was made of carefully, niftily crafted sponge. 

She insisted on going back the next day, this time urging her brother to get the same ice cream dish in order to triple their penguin collection. 

At least 2 of the penguins survived into the new millennia (possibly even outliving the café they were from?)

And now, one still remains.
