This is Mr. Pickle, also known as the ickle pickle.
You may recall that we lost Mr. Pickle at one point and I couldn't find it anywhere so finally had to order another. When the new one
arrived, Isaac was absolutely delighted to see it. He licked it for a long time,
then when he needed to go out to go potty, he insisted on carrying his
pickle outside with him.
But Isaac loves it.
It is also really durable. Isaac is a champion chewer, after all, and Mr. Pickle does not even have any tooth marks.
