Watermelon!?

"Watermelon?!" - Most of the people confronted by this spell

You say, "WATERMELON" and summon a mighty watermelon to smash against your enemy's face.

A watermelon appears anywhere within 20 feet of the caster. It then speeds to the nearest enemy, smashing their face. If the enemy is small or tiny, it is instantly killed. If it is not, the creature is dealt 1d8 bludgeoning damage. The watermelon then explodes, shooting four seeds in random directions (use d8 to determine). When a seed hits stone, concrete, or other similarly hard things, they ricochet. When they hit anything else, they lodge in it and deal 1d10 piercing damage (the caster can be hit). If the enemy survived the watermelon, they can still be hit by the seeds.
