The next sprite will have the same properties as the last sprite, that is, if you set a sprite's depth que to 400 the next sprite will have the same depth que as well. If you give a sprite a brain 6, the next sprite will have that brain as well. That's why it's important to remember to change the attributes when you change the type of sprite you're putting on the screen.

Paul's Sprite Replacer is excellent for fixing a lot of mistakes like that.
