The coolest member of the so-called "little 5" and one of my favourite chelonians is the leopard tortoise.
They come in two flavours; normal....
The second tortoise appeared to be a burn victim. I say victim but other than his horrible appearance he seemed utterly unphased by the injury and was doing his leopard tortoise thing (their thing seems to be walking as quickly as they can in a straightline ignoring a) people, b) other things, c) the obvious stupidity of their chosen route. Maybe they just know where they're going.
They get pretty big too.
