So yeah, I decided to test out the object sequences just to see what they all were, and to tell you guys what they are.

Note: this was tested with a Goomba. Results may vary depending on the enemy.

0 - Runs away, then comes back facing backwards, and uses Gunk Ball and glitches up the game. This one's quite weird...
1 - Nothing, I believe.
2 - Enemy pauses for a second or two. Good for making delays in battlescripts.
3 - The enemy's current death animation, as determined by its sprite behaviour.
4 - Does enemy's recoil animation 3 times.
5 - Same as 1?
6 - Does enemy's recoil animation once.
7 - Water spout sprite appears above the enemy. I think this one was used by Belome when he clones a character.
8 - Boomer turns red
9 - Boomer turns blue

And I believe the rest of them are nothing. Please tell me if any of you guys find anything new within sequences 10-255.

Hope this helps!!

I don't even know what I'm actually doing anymore... will I ever finish a hack?
