Fridge Walrus

Where d'you keep a walrus
When he's far away from home,
Where snow and ice are absent
And you mustn't let him roam,
But the freezer's full to busting,
While you're warm as toast yourself?
You sit him with the yogurts
On the fridge's middle shelf.

This little walrus was a Christmas prezzie. He calls out a variety of phrases whenever we open the fridge door. He greets us and, I believe, exhorts us to close the door. I'm not 100% sure exactly was he says, though, as he speaks Japanese!
