Doctor Who: 10 Secrets Of Skaro You Need To Know

10. It Features A Polluted Lake Full Of Horrifying Creatures

Just like our own planet Earth, Skaro is an enormous melting pot of climates, geographical features, and ecosystems, and as you'd expect from the planet that birthed the Daleks, a lot of these are quite deadly.

Case in point: the Lake Of Mutations, which, as its name suggests, is a toxic lake that has mutated the creatures that live in and around it, making it an extremely dangerous place to pass through - even for the Daleks themselves.

This lake first appeared all the way back in Doctor Who's second serial, the Daleks, where a small monster with glowing eyes rises from the water and terrifies Ian. The Thals who are accompanying Ian soon make it very clear that the lake is a place they should avoid, wisely deciding not to cross it.

Since this story aired back in the mid-1960s, we've learned that other creatures - like the two-headed, dinosaur-like Terrorkons, as well as some giant electric eels - also call the Lake Of Mutations their home.

Basically, you're better off taking your chances with the Daleks, rather than facing this nightmarish body of water.
