Crispy Honey Block

Lava touching liquid honey bakes it into this, which is why it shows up around jungle hives where somebody has already broken something they should not have. It survives being dropped into lava, unlike most low rarity items, so it is safe to haul around a burn pit or use as the floor of one.

In the bee themed seed and the combined one it generates everywhere, so it stops being a curiosity and becomes a default building material whether you wanted it or not. In the two harder seeds it turns hostile: standing on it sets you on fire, and roughly half the time mining a block releases lava into the tunnel you are standing in. Dangersense flags it there for that reason. Mine those from the side with a solid block between you and whatever pours out, or just leave them alone.
