Aslefshrugged spotted these on the Central Line on Sunday "Are they deer or dogs? No idea but when I changed ends at WER today there was a whole car full of them. I love this city." There's more pictures on his blog.
It's not an isolated outbreak though. Lee Sankey said: "I was greeted by the following scene as I entered the last carriage on the Northern Line at Waterloo."
Like Aslefshrugged there's more pictures on Lee's post.
"How fantastic! Whoever you are, more please", Lee concluded. Yep more please!
He said "No one seems to be amused by the balloon animals in the carriage. There is no pleasing some people." It pleases me & all the other people who RT'd the post on Twitter. If you've seen any more let me know. Cheers!
