Pi

Pi is a property.

Effect
Effected Enemies (Enemies with this property) give you Pi money every second, and when deleted, they give sum 9001*pi*pi(x)*pi(pi(x)), x=0 to 25.

Effected Enemies can't have the Halfent or Halved property, because Pi is irrational (can't be expressed as a fraction), or the Rootent, as Pi is transcendental (not root to an algebraic number).

Appearance
Enemies with this property are twisted into a Pi symbol.

Trivia

 * This is the first property that enemies give money.
 * This is also the first property with irrational numbers.
 * This is also the 6th property with twisting shapes.
 * This is also the first property that uses TRANSCENDENTAL numbers.
 * The last (currently) property I make will be Halved.
