The piggy bank game

Okay i was relaxing in fm with beat when an idea hit me
Since the boss maps don't work properly i have idea to use them for an epic npc


Npc could be placed in an fm room like room 1 where there's a lot of  room
what it basically is a game where you put in the wiz coins [useless item atm]
to activate it you have 3 different levels Bronze, Gold, Platinum each will spawn different intensity of the bosses and thus give stronger versions of the reward
Bronze :10 million hp
Cost : 100 wiz coins
Reward for Bronze : 5 rbs, 5 Fame, 5 Million Mesos, 300 Wiz Coins  
Gold : 100 million hp
Cost : 1000 wiz coins
Reward : 10 Rbs, 10 Fame, 10 Million Mesos, 1000 Wiz Coins
Platinum : 10 trillion hp
Cost : 2000 wizcoins
Reward :20 rbs, 20 Fame, 20 Million Mesos, 5000 Wiz Coins

Okay now that we got the tiers out of the way
What the npc is ""when you put the coins in my mouth and twist my nipple"Thanks beat =3"
you active me i tell you would you like to be warped to custom boss map
and a warning if you die in there, you will lose all your wiz coins Also the monsters are Buck wild. Would you like to fully purple nurple Pimppi?
Click Yes to Proceed take the chance for a Win
Click No to Cancel Hit the high way little one you might wet your pants
Each tier will have a different different mobs to choose from
Teir 1 : Mush mom > Dale > Rog > Pixie King Ect.
Tier 2 : all the hard bosses  Zakum > Horntail > Pink Bean > CWKpq > Scar ect
Teir 3 : all the hard bosses chaos version
Also remember the hard bosses have more then 1 body part each part should have Appropriate hp for example Horntail wings, arms each head body legs and tail all have the Appropriate hp same with pink bean and the statues barrier ect.
the monsters will also drop equips at a low rate basically the same drops but the Bronze, Gold and Platinum versions
Bronze : add 500 each stat
Gold : 1000 each stat
Platinum : 5000 each stat
these items should be sell able in fm shops using special fm shops
and you need to use wiz coins to  buy from these special fm shops
or maybe possibly trade system would work for this since its another useless thing LOL?
so you see this  you see will do 3 things
1. Give people something to do with the coins and time
2. Add value to Wiz Coins
3. Hopefully add another cool custom to the server
Also all requirements, rewards, npcs, items, and costs can be changed it was just an idea
Let me know what you think of my idea thanks =3
