Yep looks like a bell pepper to me. but can you get a pic of it next to your hand for size reference so we can see it a little better? as far as curling some of my bells especially my big Bertha bell peppers tend to curve sideways. Unless some how you got a mutant hab that grows as big as a bell and as hot as a hab. and if so all of us on this forum would love those seeds lol

Lol i would love to have a mutant habenero plant. Anyways, here the picture! and there was a typo in the original text, it is THREE inches in length and about 4 around.
