Because Virgil making everyone something anonymously is overly used.

Logan patted down his hair, having spent a few hours on touching up the robotic dog before him. He set himself up to the task of making everyone a robotic pet and here he was, finishing Patton's. The dog was the exact one Patton wished for, a little Pomeranian-Husky  mixed breed. On the work bench next to the dog sat a cat for Virgil and a dove for Roman that had taken him months to finish because it had to be just as good as a real one. Logan leaned back in his chair and smiled. He flicked the switch and the dog stood up. It barked playfully and leapt around the table, chasing its tail. Logan grabbed the dog and turned it off. Virgil's cat was next. The small black kitten with smudges of silver under its eyes and on the tips of its ears came to life and jumped onto Logan's lap, purring and rubbing itself against his stomach. Logan smiled and turned it off. The dove was last. He let the bird fly around the room and sing one of the several songs he had programmed it to sing before deactivating it and setting it back next to the others. Logan grabbed the boxes for the animals and set them on the desk. Logan set the androids' time zone and set the time for them to automatically power off and on before placing the now "sleeping" animals back in their boxes and carrying those boxes downstairs as well as the three for the gifts that had his name on. Matching bracelets for the anonymous gifts to follow so they had an owner. Logan smiled and headed back up to bed.

Morning came and Patton rushed downstairs early, waking everyone else and pulling their dishevelled forms from their rooms into the sitting room. Logan smiled when Patton picked up the gifts for Roman, passing them to the prince and smiling broadly. They opened their presents in order before Logan pointed out the three boxes still under the tree. Patton gasped and reached for one. Logan smiled and passed it to him, pressing his ear to the box.

"Careful, whatever's in there sounds delicate and breakable."
"Thanks Logan!" Patton took his box and Logan passed the other two theirs. Patton gasped when the puppy bounced from the box and lapped at his face. Virgil's eyes sparkled when the kitten leapt into his arms and rubbed against him, purring loudly. Roman stared on in wonder at the pretty dove that perched itself on his shoulder and sung sweetly along with him. The others looked at Logan, smiling brightly and trying to cover it up with his hand.

"Logan?"
"Yes, Virgil?"
"Where's your pet?" Shoot, he hadn't thought of that.
"I guess the mystery creator didn't have the time to get me one? They look... they're androids. It must have been hard to make three, let alone four, in the span of one year."
"They're robots?"
"Brilliantly designed too, the fur looks... if I may?" Logan reached towards Patton's puppy, brushing the fur he knew wasn't real but was designed to look that way.
"It's so realistic..." he murmured in mock wonder. The others were staring at him with stars in their eyes.

"Logan... you made these, and all the other gifts, didn't you?"
"I... I did."
"Why are you treating it like a bad thing? We loved those gifts."
"I enjoyed seeing you so overjoyed at something so simple, at seeing your faces when you opened these gifts from supposedly no one, hearing you thank this mystery person for something as basic as a lava lamp that played music or a pair of headphones that glowed in different colours dependent on the tempo of the song you played."
"This was amazing, if we had thanked you sooner we might not have gotten these adorable darlings so I'm glad we missed the clues long enough."
"Yup"
"Pancakes anyone?" Virgil asked, standing with his cat at his feet. Patton reached for the kitten and pet it softly.

"Finally, a cat I can pet!" Patton squealed, rubbing between the little thing's ears and eliciting more purrs and nuzzling from the cat. They enjoyed spending time with the pets and Logan realised he should have given Patton's puppy a quiet mode.
