Sorry I haven't updated in a while, but you know… craziness… Anyway, Kululu's going to push a reset button on his plan (not literally) and wipe everyone's memories to start his trick over, this time, hopefully, without glitches. Here we go!
The aforementioned face was twisted into a concentrated grimace. He was working furiously at his computer, trying to detect a problem that didn't exist. Kululu grunted, sitting back in his chair tiredly. Androids were so complicated to control. A memory-manipulative syringe? No problem. Genetic engineering? No problem. A robot baby? Massive problem.
Suddenly something in Kululu's head engineering? A memory-manipulative syringe? That was it! Why didn't he think of it before? (Although, as you'll soon see, he did think of it before, and probably beat himself up for days afterwards for not just starting it off with this. He quickly got to work, setting off upstairs within half an hour with a new batch of syringes, a gas mask, and his trusty universal remote/iPod thing.
A click of a button later, and everyone, invited to dinner by Natsumi, and even Aki for a change, passed out from inhaling sleeping gas, even before anyone who hadn't been drugged had a chance to ask why Giroro was cooing at a baby and trying to get her to stop crying- not exactly something he did on a normal day.
He went about giving everyone(including Giroro) a shot, pricking Natsumi and Giroro for blood samples, then taking Kioshii downstairs with him to do some- shall we say- tweaking.
After turning the squirming robot off, he carefully scanned her. After still finding no real problems with her internal wiring, he decided to go through with his plan. Pulling out the blood samples, he slid them into a big machine over in the corner. He went back upstairs while waiting for the machine to do its job, and used his universal remote to teleport everyone back to their respective homes. He should probably tell Keroro that he could do that, but where was the fun in that?
Then he waited for nightfall. The Hinatas had all gone to sleep, after the initial 'what happened and why can't I remember anything about the last few days?', and Giroro was in his tent. It was funny to think that he, Kululu, was the only one who could remember the android. The drug he'd given them didn't create memories for them, it erased the ones they already had from the first drug. His first attempt at a prank on Giroro had failed, but this time, for sure, he would succeed. And this time, it would be a trick on EVERYONE, not just Giroro. And, in a way, a birthday present for Giroro, as his birthday, which was coincidentally on Riku-gun Kinen'bi (I made this up; his birthday isn't specified in the series… look up "Riku-gun Kinen'bi on google WITH quotation marks; it's Army Commemoration Day), was the next day.
He waited another ten minutes for his machine to finish up, then got an egg-shaped baby carrier with his insignia on it. Gently placing the sleeping baby into her carrier, he got out some stationary and a pen and wrote, "Happy Birthday, Giroro. It's just for you and Natsumi!" in big, curly pink letters. He taped the note to the carrier and closed it, forming a complete egg with no visible seams, just the handle, and teleported himself and it outside. (There's no way he would've been able to carry it. It's almost as big as him!)
He shoved it so it sat right outside Giroro's tent, impossible to miss, confident that this time, at least for a few days, it would be interesting to watch. Eventually he'd come clean about everything, of course; where's the fun in anything if you don't get beat up at the end? Then he took the long way down to his lab, taking a small detour to Natsumi's room to place another note.
"Congratulations, you're a mom!"
