Hai i was playing the PSP2 demo and i figured out a funny trick!

If you place a total of 10 decorations (counts if you remove and place) then you will get an title get the reward and it will be a Moatoob Bird. After go up to it and keep saying what you want it to say. I got my bird to say "I want a cracker!" Hello." and "Hai there pretty girl!" It's pretty cool!
NOTE: Be patient you need to say it like 15 times then wait a minute or two then he will say it and remember it and say it at random times!)
