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.
If you're looking to enter the #wanderingwalrus competition, there's no better place to pick up your own cuddly travelling companion than the Horniman Museum shop.
The Walrus toys sold in our shop aren't modelled after just any Walrus. They've been specially created to celebrate the wonderfully unique shape of the Horniman Walrus himself.
Notice the resemblence?
When our Walrus was brought to England in the 19th Century, Victorian taxidermists had never seen a live Walrus before. They had no idea about the skin folds which should appear around the chest and neck, which resulted in our Walrus getting a little 'overstuffed' and standing rather tall.
Our Walrus cuddly toys have been deisgned to have that same upright, wrinkle-free look.
They come in two different sizes, so you have a choice between a Walrus mini-me and a mini-mini-me.
Who knows where the walruses will wander to? Here are some ideas to get you going.
This walrus has travelled beyond Margate and Britain's shores, all the way to Paris to gaze upon the Eiffel Tower.
This walrus has plunged into the depths of the tropical Pacific Ocean, a very long way from a walrus's usual habitat.
And this walrus is enjoying the crystal clear, beautiful blue Alpine waters at Attersee Lake in Austria.
So the only question is: where will you take your #wanderingwalrus?
To enter the competition, you can tweet, instagram or upload your photos to flickr using the hashtag #wanderingwalrus. You can also email them to email@example.com. We're looking forward to seeing your photos!
While many of you have been following his progress with our liveblog and on Twitter, Acapmedia have been filming the whole event. They've produced this fantastic timelapse film documenting the Walrus leaving the Natural History Gallery for the first time since 1901.
The Walrus will be away until September, but until then you can visit the Natural History Gallery and leave a message for him on the Walrus Wall.
We're very happy, relieved and glad to report that our wonderful walrus has been moved successfully. He's currently being packed up in a crate in advance of his trip to Margate. Here's a short video of him in the air - we'll have a longer video about the whole procedure later in the week.
9.15am, 14 May 2013
The Walrus has spent the night on his new platform at the front of the gallery. Today he will be carefully packed by the Conservation team and safely crated up ready for his journey to Margate.
The first task for today is for our conservation department to check the Walrus's condition, and make sure he's ship-shape for his trip to Margate.
Our famously over-stuffed walrus, weighing in at just under one ton, has been in our Natural History Gallery since 1901. Since then, he hasn’t moved more than 25 feet, so getting him out and on his way to the coast is a huge task for museum staff to organise.
Our conservation department has been working with specialist art handlers to ensure the move goes as smoothly as possible. Preparations are under way: the Walrus has already received his annual clean, and the larger pieces of his iceberg are being moved away.
The biggest challenge is the need to lift the Walrus out of the gallery over the other cases. The Natural History Gallery will be closed to the public next week while this is happening, but we've put together some simple sketches to help you picture what will happen.
The Walrus will be lifted on Monday 13 and will leave the Museum on Wednesday 15 May. The Natural History Gallery will be closed throughout, so this week is your last chance to wave goodbye and wish him well on his holiday. He'll return to the Museum in September.
Be sure to follow the Walrus' journey on Twitter, and keep an eye on our blog, as we'll be live-blogging throughout. You can even catch up with the Walrus' own comments @HornimanWalrus.
