Im in the middle of doing some work on my Cyclone as well and noticed a similar thing happening at Planetary Pinball - they have the rabbits in their Cyclone section too

Is there a possibility the rabbits were used on early production to use old stock & then they reverted to the Bad Cats targets later on? Those cats are on Bad Cats as well.

If you haven't got them already i'd recommend trying to locate a the promo clown set that was made for this table. We have on our table and placed one (cowboy) on the base of the left Ferris wheel ramp and the other (Flasher) in the middle exit on the Comet ramp. Does cause a few blindspots, but i think it looks great
