Crazy Dave took all plants to the Zen Garden for the special announcement he wanted to say. He carefully announced that he had found a…taco! A beautiful taco. And he ate it in 1 bite. Of course, all the plants were very angry that he had wasted their time. But it happened often so they weren't surprised.

"Psst. Peashooter." Sunflower whispered. "Come over here." Peashooter looked to his side. There he saw Sunflower nearing the exit while no plants were looking. He decided to follow her. They made it outside and decided to visit the graveyard where the zombies are usually created.

That was a huge mistake. They found a giant hole in the graveyard and wanted to explore it after being there for a few hours. Suddenly, a huge horde of zombies came after that to protect their territory. It was huge, and Peashooter couldn't fend them all off. They quickly ran back to Crazy Dave's home, almost becoming zombie food in the process. The lawn mowers killed all the zombies and they got back home safely.

They do not know what they were thinking when they did that. The mushrooms caught them outside during night time once they arrived back home. "Peashooter? Sunflower? Why are you guys outside during night?! You guys are supposed to be asleep! It's our night shift." Fume-shroom asked. "Yeah, you guys can't be out here." said Puff-shroom. "Go and head to bed while we defend for you, ok?" Peashooter and Sunflower nodded and head to bed. They barely got any sleep because they wanted to explore that strange hole in the graveyard. They fell asleep and Peashooter dreamt of what was in the hole.

"A rubber ducky? No…that can't be it. Hmm…maybe a giant brain? No..the zombies would've already eaten it. Or maybe a giant machine..so many possibilities. We have to explore that hole, if we don't find what's inside it, something may happen…"
