which BALL are you?

Here are the 3 balls that I've got for DiDi.
Which one is your preferance?

• the limo-green?
• the egg-yolk yellow?
• the pink-green ball with bell?

I personally like the pink-green ball? why? As it has bell inside. It's pleasant to hear the "ling~ling~" sound when DiDi is playing with it. The "ling~ling~" sound just fit cute DiDi well. Somehow it reminds me of snowball, I wonder....................................
