tumbeasts

Tumbeasts are creatures found on tumblr. They roam the data centre and help run tumblr, though sadly they usually go un feed, which causes tumblr to crash. They are often irritating due to how much they come up.

We may have forgotten to feed the wild Tumbeasts that roam our datacenter, resulting in gnawing and/or mutiny. Animal control has been alerted.
