Im sorry you lost your tama! i lost mine to! well, here are a couple of tips:
1 Did you lose it at school?...Tell your pricipal, and hopefully she will tell you if it appears in the office!!
2. Lose it in your house?...Search Search Search!!! Look everywhere you can think of! You just might find it!(look under beds, tables chairs...)
Or ask your mom or dad if they have seen/found it.
3. Lose it outside?...Ask your friends!! If you have good friends, and they might have found it, they will probably tell you. If they say no, yet you see, in any mark( stickers on the back of tama...) that it looks exactly like yours, and has your mark on, question them, maybe go to their parents just in case.
4. Lost it anywhere else?...Im sorry to say all you can do is hope! maybe it turned up somewhere? All you can do is hope!!
