Eight Wonder

Extra clever earthbound spirit
Ghost in the form of a mongoose
And I have hands and I have feet
I'll never die, I am a freak

Hello, I'm here, I'm living in the wall
I know, I might be small but I am a freak

Thou wilt never know what I am
I am the fifth dimension and I will split the atom
And if you see me, you're paralyzed
Pillar of salt, you're mummified

Hello, I'm here, I'm living in the wall
I know, I might be small but I am the eighth wonder
