Random orbit around origin

Hi Kirupians,

I’m making a little kids game at the moment with all kinds of critters and such.
I randomly place the critters around the stage. Now to give them some more life i would like them to wander around a little bit but not stray from their origin (the place they were initially put).

Now i recon i should store their origin in some vars and then setup a timer (or an onComplete with any random tweening engine) and then get new random coordinates to tween too that are within range.

I think.

I’m not sure if i’m on the right track as i can’t get this to work properly so far. If i could be nudged in the right direction that’d be great. (brownie points for examples!)
