I have a level I am building where I am trying to use Lakitu. But, for some reason, no matter what I do, when Lakitu appears it warps me to a completely different world just like a warp to level sprite (no not a warp cannon). I do also have a warp to level sprite in the level. I know how to make warp to level sprites and set up Lakitu and the zone etc. All settings are correct as well. I have had this happen before in another level I was building too.

How do I keep Lakitu without warping?

LOL.
This is a weird issue...
Also, are you sure that you have no weird sprite data bytes in both the Lakitu and the warp?
Check also that the warp has the right dimensions and so on

Post the .nml if you want, I'll try to have a look

I am positive that all settings are correct.

I had it too once!
Are you sure to have set the "SPINY" enemy in your Sprite Set?

This has solved my Lakitu warp-problem!

Tutorial vor REV94 (still my fav):
Open Level Configuration --> Go to Sprite Sets --> set BOX 4 to "1" [Lakitu (40,183] and BOX 5 to "1" [bullet Bill/Bomb (27, 28, 37, 55, 241, 243, 252)

And uncheck the box in the Lakitu sprite!
