Don't know where this whole otter and hedgehog thing started.but it amuses me, and this is adorable. - THIS IS SO CUTE! Also, the whole hedgehog and otter thing began when we saw that they looked like those animals. I find it cute and funny.
Toby was, of course, the talented and adorable dog on the Granada Holmes series, and Gladstone was John's dog in the RDJ/Jude Law Holmes movies. A gladstone is a type of doctor's bag from the BTW. (Toby is also the name of Molly Hooper's cat)
