Of course, we already knew how important our over-stuffed star is, but the heart felt messages really drive home just how much he is loved by all our visitors. We thought we'd share just a tiny selection of our favourites here.
We've seen some truly excellent artwork.
And puns abound.
The Wall definitely proved that the Walrus is popular with all ages.
He even had his first (we think) marriage proposal.
Some people were understandably disappointed with his absence.
And it all got a bit surreal for a while.
But most simply wish him well on his first trip outside the Natural History Gallery since 1901.
The best part of the Walrus Wall has been the brilliant stories people have shared with us.
Don't forget to make your own visit to the Museum and get your message out to the Walrus before he returns in mid-September. If you're lucky, you may get an answer to any questions from the Walrus himself.
You can see plenty more from the Walrus Wall in our Flickr set.
