Since you're doing pokèmon headcannons, could you do the Mareep line or the lilipup line. You don't have to but I would really appreciate it.

• Farm Mareep are often allowed a wide range of space to graze in. Because they’re hard to control in large groups, and the farmer cannot train them all individually, herding pokemon may be employed. Although a sturdy and smart pokemon like Herdier may seem like the obvious choice, it is expensive to get them in Johto, where there are the most Mareep herds.
• In Johto, the most popular pokemon for herding mareep is diglet, as they are resistant to a Mareep’s naturally shocking coat. They can also move very fast in the ground, able to nudge mareep by their feet without scaring them. Jolteon and Manetric are also good choices for their resistance to Mareep static, but are difficult to get.
  
• When frightened, herds of mareep clump together and form a sort of “thundercloud” to fend off foes.
  
• Trainers are advised to brush their Mareep often with a special brush to avoid getting shocked by them. 
• Mareep spook easily, so it takes patience for a Mareep to get used to someone. They might release small bursts of electricity when frightened, so be very careful!

• Flaaffy are very popular among trainers, and are less likely to shock by accident than Mareep. It’s still recommended to brush them. It’s wool also produces a nicer quality fabric than mareep.
• The orb on Flaafy’s tail glows when it is excited or has fully charged electricity. When they shake their tails, it makes an odd noise.
• Farm Flaaffy that evolve into Ampharos are often lended to lighthouses, as they no longer have any wool. However, by the time they’ve evolved, their farmer is likely pretty attached to them - using Ampharos to light the way during night.
• In dangerous areas, like mountainsides and cliffsides, people who live in outposts often have an ampharos as a beacon to guide people to safety. The stripes on lighthouses are even designed after Ampharos’. In fact, an Ampharos is recognized as a symbol of safety and help all around the world.
• The gem on Ampharos’ head glows when it is content, and is pleasanly warm to touch. They may press it up to their trainer affectionately.
