Make Queen spawn larvas from her ass?

[Kabel]

When the queen morphs a creep tumor is comes out of the back parts of her body. I am trying to create an ability that lets the queen "push" out a larva from her ass. (Just like she pushes out a creep tumor.)

The ability will be clickable, you just have to click it and the larva will appear. But I would like that sweet animation as well. If the larva just appears next to the queen it will look odd.

How can this be done?

Same way the queen makes a creep tumor except that it will target a generic point instead of a specified point. Be aware that the larva will not become owned by a hatchery.

The larva can be solo on the ground. That is fine with me!

{EDIT}
Hm.... 3 things:

I can´t get it to be a generic point. I still have to target it on the ground.

It does not come out of the ass. (Like a creep tumor does)

A red error message appears: "Larva is missing a buildable ability"

Am I swimming in deep water now? O_o

You will probably need to change the ability to one that is instant.

Actos will control this.

Might be the larva expecting to be attached to a hatchery but is not. Can the larva morph into anything?
