Memory is very plastic, and constantly changing. Unused connections are abandoned and repurposed, and connections that see lots of traffic are reinforced. The caveat is that the more connections your brain curates, the less energy is spent on reinforcing any particular one. Large datasets like the names of pokemon are subject to this. the brain has a hard time reliably retracing every connective pathway to recall every related memory in that category. The less individual things related to a common memory topic there are, the stronger their interconnection through relation is. That's why it's easier to remember a phone number than a credit card number. Memory is very weird, but it plays by a somewhat predictable set of vague rules
