What about pear flavour or mango? Lychee? Grape? Grapefruit?
Gooseberry? Cranberry? There are actually many fruit different flavours
they could do still.
I once had an alcopop that was a mix of cactus flavour and something
else. It tasted weird and I've never seen it again. Maybe they should
make that a Kitkat flavour, Kitkat Cactus, I can picture it now...
