How to properly add zombie_arise effect to zombies for round-based zombie game?

I tried using the _use tag to make it work

nzombie_base{
  _override:b=yes
  _use:t="zombie_arise"
}

The animation was played when the zombies were spawned, but they just stood there for the rest of their lives.
If i change it to _extends, the zombie will move, but the animation is never played
What did I do wrong?
