Rulings
The token copies exactly what was printed on the creature and nothing else (unless that creature was copying something else or was a token; see below). It doesn’t copy whether that creature was tapped or untapped, whether it had any counters on it or Auras and/or Equipment attached to it, or any non-copy effects that changed its power, toughness, types, color, and so on.
If the copied creature had 
in its mana cost, X is 0.
If the copied creature was copying something else, the tokens enter the battlefield as whatever that creature was copying.
If the copied creature is a token, the tokens created by Kiki-Jiki’s ability copies the original characteristics of that token as stated by the effect that put it onto the battlefield.
Any enters-the-battlefield abilities of the copied creature will trigger when the tokens enter the battlefield. Any “As [this creature] enters the battlefield” or “[This creature] enters the battlefield with” abilities of the copied creature will also work.
