The Thomas Easter Egg Train is a good price once again on Amazon. You can get this for $12.99 and shipping is free with Prime/AmazonMom or a $25 order.
I believe the little chicks and eggs sing when you push them so this should be a really cute little train.
The reviews are excellent- head over here to have a look.
(Thanks Coupon Geek!)
My son is 4 yrs old, and he loves Thomas! Imagine my surprise when I found this same train at TJ Maxx today for $9.99!! So, if you have a TJ MAxx nearby, you might want to check it out!
