Why do items such as cucumbers or pickles exist in TB wht do they do?

They are collectibles items, it's just something which, when you buy them, you can say "Yeah. I have a cucumber in my inventory". Such as buying expensive gold stuff which aren't pretty much stronger than another thing on a mmorpg, it looks cool and that's all.

if you are a collector,you need them.otherwise,ignore them.

they are pretty much quite useless,other than being able to say "hey,look,i have a pickle i wasted some dollars on".literally

if im honest,they probably are more of a bait for players to waste their money in

That and they were also used to get an achievement

But they are mostly here for a collectors item.
