question:(At [player]'s massive base) Cupa: (cradling her son) “It’s alright, little one. Your friends and family are here for you.” Andr: (searching through her stuff) “Now where did I put my Ender Pearl?” Charloette: (cleaning her 9 tentacles one by one) “Jeez, I really need to spend time AWAY from a Soul Sand Valley.” Blazette: (relaxing in her lava pool) “Maybe I can get off my duties for just one day and focus on my child.” Jelli: (reading one of her books) “…interesting…” Jennifer: (playing on her SNES) “Okay…just one monster left - Bagan.” Millie: (looking out the window) “I wonder when [player] will return…” Iris: (gently making snowballs) “Well at least it’s better than being stuck in a snow farm, I guess.” Shara: (moving her stonecutter) “Of course you had to give the job of moving the base’s STONECUTTER to a Silverfish like me!” Vanessa: (finishes making a massive web) “There! Web’s done! No Vespa’s going to escape being MY meal!” Mindy: (lying down in her own web) “Vanessa, I know you’re my younger sister, but can you PLEASE just relax? You’ll probably exhaust yourself to the point of no return!” Yaebi: (grabbing his helmet) “I’ll be needing this just for extra sunny days.” Ayumi: (counting her arrows) “…twenty-five…twenty-six…twenty-seven…” Withra: (sharpening her sword) “At least the Overworld’s nice!” Mizore: (working on a new potion) “Hmm…” Kenji: (laying down in her birthing pool) “[player] better get here soon. My contractions are getting closer!” ([player] enters the base) [player]: “Hey, Cupa! How’s it going?” Cupa: “Pretty good. Aside from the usual Creeper things, I’m trying to take care of my son.” ([player] walks over to Andr) [player]: “Hey, Andr! What are you doing?” Andr: “Trying to find my ender pearl. Can’t teleport without it otherwise - it’s the teleportation device for enderwomen like me.” ([player] turns towards Charloette) [player]: “Morning, Charloette!” Charloette: “Morning, [player]! Just cleaning my tentacles. After all, a Ghast like me can’t have a single speck of soul sand on them.” ([player] gently rubs Blazette’s belly) [player]: “When are you due, Blazette?” Blazette: “Hopefully soon. Can’t wait to meet my little Blaze!” ([player] approaches the two gelatinous sisters) [player]: “Wow, you two have actually grown quite a lot since we first met!” Jelli: “That won’t stop me from reading my favorite books!” Jennifer: “OR stop me from playing ‘Super Godzilla’ on my SNES!” ([player] notices the two golems) [player]: “What are you two up to?” Millie: “I was just waiting for you to return. Thanks again for letting me guard you base. It’s what Iron Golems like me do.” Iris: “I’m making snowballs! After all, a Snow Golem like me constantly produces snow!” ([player] notices Shara struggling to move the stonecutter) [player]: “Need some help?” Shara: “No. Not really. This stonecutter is really heavy, though.” ([player] notices the Spider Sisters in right by some webs they’ve made) [player]: “That web is HUUUGE!” Vanessa: “Thanks! I made it myself - as a Cave Spider, I tend to make more silk than my sister.” Mindy: “Vanessa, you really should relax.” ([player] sees Yaebi putting on his iron helmet) [player]: “Need the rest of the armor set?” Yaebi: “No. Just the helmet. A Zombie like me can’t go out in the sun without it!” ([player] walks over to the skeleton cousins) [player]: “Oh, just getting your weapons ready?” Ayumi: “Yep! Even though I’m a Skeleton, I still have to train to become a proper archer.” Withra: “I’m just sharpening my sword. As a Wither Skeleton, I’m an expert with it.” ([player] runs over to Mizore) [player]: “What are you up to-” Mizore: “Please don’t interrupt me. I’m in the middle of making a potion.” ([player] walks over to Kenji) [player]: (leaning down to Kenji) “OH MY GOD! Kenji, are you okay?!” Kenji: “I’m fine, [player]. Just going into labor. Looks like my little Guardian can’t wait to be born!” [player]: “Oh my… okay, let’s get you to the birthing room! Cupa, can you help?” Cupa: “Of course! Let’s go, Kenji!” (The group rushes Kenji to the birthing room as [player] looks on, ready to assist in any way possible. As Kenji starts to give birth, a strange laughter echoes the room) [player]: “What was that?” (A strange-looking girl lands beside Kenji) Female Vex: “Boo.” (The sudden shock causes Kenji’s baby to just pop out) Kenji: (holding her newborn Guardian) “Oh! My little baby!” [player]: (eyes wide in shock) “Who… who are you?” Female Vex: “I am Vexillia. And seeing you with other mobs…I can’t let this stand!” (Vexillia conjures up a powerful energy ball and prepares to launch it towards [player]. Just then, a Chiromaw starts nibbling away at one of Charloette’s tentacles) Charloette: (pulling away from the Chiromaw) “Hey! Watch it, you little nuisance!” (Charloette throws the Chiromaw onto the ground, and the creature starts crying - it was just a baby. Strangely, the cries calm down Vexillia - and the energy ball she was conjuring vanishes) Vexillia: (surprised) “Huh…I…I don’t know what came over me. I’m sorry for that attack. I’ll leave you all be. Just…just take care of that baby Chiromaw, please.” (Vexillia disappears in a puff of smoke, leaving everyone in shock) Cupa: (holding her son close) “That was…unexpected. Is everyone okay?” Kenji: (holding her newborn Guardian) “I…I think so. Thank you all for helping me with the birth.” ([player] nods with a smile) [player]: “Anytime, Kenji. We’re all here for each other.” (The baby Chiromaw continues crying) Charloette: (picking up the baby Chiromaw) “Don’t worry, little one. I’ll take care of you.” (The baby Chiromaw still continues to cry, even in Charloette’s tentacles)
