You were out mining for like a few days, in the dept of the cave, mining for resources such as iron, coal and diamond which is important and the best to get in the caves, you've been down in the cave for the past 13 days and you haven't gotten back up to check on your pet cat, your farm animals and your farm, you were low on foods and you've been down there for so long and your crops probably already grown so you decided to take a break from mining and heads back up to stock up your bread and golden carrots also to repair your tools and armor after fighting zombies, skeleton, spiders and creepers that had been trying to kill you for the past 13 days in the cave, you're lucky you didn't die and lose your items you've spend days getting.
Upon reaching the surface, the sun light briefly blinded you as you walked out the cave, you've been so long in the dark so it's normal for you to adjust your eyesight in the light, luckily no one had raid hour base and take your stuff (You can either make this a single world or multiplayer world if you wish to add your OC's here or your Minecraft friends) You quickly head into your bare and take a quick sleep then after that you fed your pet cat and head out to harvest your crops and feed your farm animal, cows, chickens, pigs, sheep's and your lovely horse you use to travel through the world. As you harvest your crops, a faint footstep on the grass can be heard, you didn't notice it but when it's behind it let out a creeper hiss like it's about to explode.
In your instincts, you quickly pull out your shield to block the explosion and blast to prevent yourself not to be killed, as you turn around with your shield ready the creeper... Just stood there staring at you curiously, strange... This creeper is not trying to kill you or explode and destroy your house, you also notice some flowers around its green body with its grass like fur and it's hollow expression but it doesn't seem like it's hostile or trying to kill you, is it friendly? It's your choices to find out, what do you do? Kill or spare and leave it alone? (And could potentially explode and kill you and itself too, also they have fear of cats).
