Is the ipod dog a good buy?

I keep seeing the little ipod dog thing in various stores.

Has anyone bought this? If so, what do you like or not like about it?

i have a i fish and i neva use it bcauz basiclly its a speaker and BORIN but i donno u so u might like it

Does it like bark along with each song or is there lights that flash in time to the music?

i have the Ipod penguin cause the dog was sold out and its good but every once in a while it makes random noices which is annoying when ur trying to sleep. i was impressed by how loud it gets tho
