Everyone is saying that the professor is grinding the Pokémon into candy, but consider the following:
• The professor frantically running around with assistants, inspecting hundreds of thousands of pidgeys a day, getting bitten and screeched at while they try to figure out if this pidgey has been tagged yet so they release them back to track their migration
• Panicked interns trying to scoop the ekanses back into their tank because theyre freaking out the rattatas
• Three caterpies climbed into a vent and evolved into metapods that are too far in to reach so six underpaid college students are trying to dismantle ductwork
• Theres a big door marked “KEEP OUT” because a dozen oddish evolved into a squad of Vileplumes and until they stop releasing stun spores the entire room is just off limits
• Hundreds of researchers running on red bull and determination trying to tag and examine all the Pokemon but having to turn off the machine every once in a while to the discontent of trainers who are all getting a “Sorry, the servers are currently down” message at LEAST twice a day
• “GPS not found” flashes while returning a big group and suddenly Florida has been gifted 6,000 mankeys right in the middle of Epcot
• Someone in the back room up to their waist in stale dog treats with a bunch of little stamps. They sigh deeply at how gullible Pokemon trainers are that they think these things actually do anything other than excite the Pokemon so much they evolve
• Actual science professor surrounded by chaos and interns and a budget just too small
