I was thinking they open a grotto in deadwood near the graveyard
You can dig the spot that has an X on it
you will fall in a dungeon
Their will be haloween tokens which are a special currency used to buy stuff from the special haloween shop
their will also be shards which will need to be collected to make a haloween token. 5 shards=1 haloween token
In the dungeon you will have multiple ways to get haloween tokens
(dungeon is singleplayer only fwI)
baddy slaying
Spar ( warps a random player who is in the dungeon into your lvl)
You will need to spar the player for haloween tokens.
