Under no circumstances are things without legs immune to the prone condition, perhaps having to MANY legs makes you immune to being trip via combat maneuver but spells and taking a free action to drop prone is still available to you. Example see Centipede.
Having fluff provide a mechanical benefit is always a bad time for all involved unless everyone in the group is on the same page and okay with it.
Thank you for letting me know Blakmane, I didn't do all the research and only typed what I thought at the time. I apologize.
Apparently having no legs makes you immune to being tripped. Although you can still have the prone condition by using a free action on your turn. Since Merfolk and other races or monsters don't have 'immune to prone' only tripping. Another example is the Command spell usage of 'Fall', these still would make the character(or creature) in question prone.
