Trigger help

I need help with 2 triggers.

1: Is there any way to disable certain animations for a model, withouth editing outside the editor. What i need is a burrowed crypt fiend, whos only animation should be the burrowed animation, I want it to be able to move whilst burrowed, but if i do, it looks unburrowed for the movement, but is in fact burrowed all the time.

2: Whats the easiest way to remove all items of a certain type from the map, as soon as these items enters the map. Im not using Jass triggers, but I think it should be possible to do it without these.

Not sure about 1, but for 2, you could do a periodic event that will pick all that item every second or so, and remove it.

Well, just check with entering playable map area and hero picking it up

Conditon: If item-type = XXX

Remove XXX

Nope. When burrowed, it uses the burrow animation; when walking, it uses the walk animation.
