A: It depends. The Creepers: Larry the Zombie, the Radioactive Potato, and the Time Bomb all move in the counter-turn direction whenever the Goal changes, however, the Time Bomb has a minor exception that makes it work slightly differently than the other two.

For Larry and the Radioactive Potato, the Goal change and the Creeper move are considered to be simultaneous. Basically, do both of the things (play the Goal and move the Creeper) and then check win conditions.

If Larry or the Potato are moving around the table preventing wins, and you play what would be the winning Goal, you need to time the play of your Goal so that they’re not going to move onto you with the play.

Conversely if the Rule: You Also Need A Baked Potato is in play such that you need the Radioactive Potato to move onto you with your winning Goal play, you’ll need to plan such that the Potato does move onto you with the Goal play. Getting the timing right to play the Goal you need is part of the challenge of having either of these on the table.

The Time Bomb in Mystery Fluxx has an exception such that, if you have the Bomb and the Body in front of you when you play the Goal: Blown to Smithereens, you can win immediately instead of having the Time Bomb sneakily slip out of your grasp just when you’ve played the Goal.

Unless you’re winning by playing that Goal yourself, however, the Time Bomb will functionally work the same way as the other two. So you’d better make sure you’re not handing your neighbor with the Body the win when you play Blown to Smithereens!

PS: Or you can plan on the sneaky Time Bomb to move to you when you have the Body, and win that way!
