Proof that the wall nut is not a potato

I've had enough, okay? ENOUGH. I will not accept my lil nut boi being confused with a potato. My little cousin said to me a day ago that he started pvz and that his favorite plant is the potato that blocks zombies.. I almost lost my temper and started frothing at the mouth.

IT'S CALLED WALNUT, WALL-NUT, WALL, NUT. A NUT THAT IS A WALL.

Yes, when the zombies eat the walnut, it cracks and you can see that it's hollow on the inside.

Exactly! The P O T A T O mine. You plant it, you wait, it sprouts, it explodes. Which means that all the potatoes in the pvz universe have explosive capabilities. Tell me one time that you saw a walnut explode and disappear. Oh wait... WAIT WAIT WAIT NOOOOOOOOO

THE EXPLODE-O-NUT IS NOT A POTATO. IT'S ON THE NAME AGAIN. Though it explodes. Does that mean that the potato race of plants takes walnuts as hostages and use them as explosive tanking walls? This is getting too deep I'm afraid.

SAVE THE WALNUTS FROM THE MURDEROUS POTATOES
