In general, the safest way to pick up an Eevee or eeveelution is to lift from its midsection, between its front and back legs, and to support it with your arms beneath.
Flareon’s body is warmer than other eeveelutions’, but not too hot to the point it’s uncomfortable to hold. However, if it thinks it’s in danger and/or is prepping for an attack, its temperature will shoot up, to the point it isn’t safe to handle.
Jolteon’s fur is prickly and easily picks up static electricity, so a lot of people trying to handle one for the first time will get shocked and drop it, so be careful.
Upon evolution, Vaporeon loses its fur in favor of slick skin, made even slicker by the moisture it collects, so it’s very slippery, especially since it may try to wiggle out of your grasp and onto your shoulders.
If someone picks up an Espeon, it will put its tail on their neck or cheek so it can sense their thoughts. Don’t try to pull away; it’ll take that as a sign that it’s not trusted.
Umbreon will be very calm about being picked up (unless it’s aware it’s in immediate danger), but will keep a close eye on its surroundings, in case it has to slip free and disappear into the shadows. Speaking to it reassuringly can help it feel safe.
Leafeon likes to be held up or ride on its trainer’s shoulders so it can absorb more sunlight.
Glaceon’s body temperature is very low, and it might try to pull away if it feels like it’s getting to warm. Gloves are recommended for both it and the trainer’s safety.
When handling Sylveon, don’t hold onto or put any pressure on its ribbons; it likes them free to flutter around and feel surrounding emotions.
Stu, let me ask you a question: how did you not realize until then that you had too many eggs? Nobody sells eggs in a big cloth-covered basket, so you must have done that yourself. That means you spent god-knows-how-long opening up twelve whole cartons of eggs, carefully placing each egg one-by-one inside a big basket, and then covering it with a big picnic cloth… and at no point- at no point- did you ever stop and think “gee, there might be TOO MANY FUCKING EGGS HERE”
