DX Full Full Rabbit Tank Bottle
 

anyone know where there is a decent price on this -ive been trying to find one -i managed to get the full bottle buster but i can't find this one

One website you could try is Mandarake. They mainly deal in used items, but I think they may have a few FullFull Bottles.

EDIT: Also, CStoys currently have the FullFull Rabbit Tank bottle for sale as well.

ya i see 2 there bit more than i like but its an option now.

update-got one so im good now.
