Tamagotchi P's have cool features, like : cooking together, can connect 4 tamas ( can connect only tamagotchi P's itself and tamagotchi iD L ) in same time, can sending mail to others, ect. I like to choose Melody Land deco pierce. It have some cute characters, like : Pianitchi ( she's my fav character ). I think Tama Circus deco pierce good too. I heard that Tama Circus deco pierce have cool features, but idk what it is, because I only have a Lovely Melo deco pierce.
