I'm not sure why you are messing with the timescales, and instead of disabling the behaviours you might want to just stop the movement an use start ignoring input, also i wouldn't use is overlapping, but use a trigger like on collision and moving the balloon 250 pixels in one tick doesn't sound like a good balloon movement..
So I guess I don't understand what you are trying to do in this event..
something like this should work:
player on collision with balloon
- player pin to balloon
- player start ignoring input
- player set animation
