DQMJ(Dragon Quest: Monsters: Joker) DS Help :D

Hallo i just got the game DQMJ(dragon quest: Monsters: Joker) to my DS lite. And i are in the finals after 25 lon hours but i cant win the finals. So i did go on [this site] and [this site]. And on the secound site i was seing the Rank X Monster Ruin where i need a mumboh-jumboe and a living statue. But i have some problems with the Mumboh-Jumboh with is Rank S i cant made it all the orders is saing i need to Fuse Mum+Boh and Jum+Boe an make an + and - Mum. And after that fuse them but i cant do it it is really pissing me of because i have spend 4-5 hours to get Jum,Boe,Mum and Boh. And now i want som information from Gamespot so please Help me.

I wil just make a little list with my problems so you faster can now what the problem is. But please Read the other first:D

1- How can i make Mumboh-Jumboe? i have Mum,Boh,Jum and Boe.

2- Do i need to complete the game before i can make rank S and X monsters?

3- Is there a special LVL they need to be in?

Please Help Me:cry:

1) MUM+BOH=MUM THEN

JUM AND BOE=MUM THEN

MUM+MUM=MUMBOH JUMBOE p.s. have you checked that they both in different "types" like - and +.

e.g. mum- and boh+ and jum- and boe+

2)You dont need to complete the game before you get rank s and x monsters. I had an Atlas rank s and Alabast dragon rank s when i fought the finals.

3)they just need to be lv 10 each for sythesising (cannot spell it).

hope this helps :D
