Appearance: a small
lemon melon tree
lemons melons, becuse why not? We have our lasers, we just need our combustable melons! Combustable melons would be thrown similar to dynamite, destroy less blocks/none at all, and set entities on fire
When hit with a fist, plant explodes. Must be picked with a special tool. When picked, plant reverts to having no fruit. If walked over, plant explodes. Possibly a combination of a plant that produces gunpowder and a melon plant. Requires light between level 8 and level 12. If under, plant does not grow, if over, plant has a chance to explode. Moderately slow growth rate.
