This is a prototype Pokédex, a device that can gather data on Pokémon for analysis.
The Pokédex records information on Pokémon encountered, such as diet, habitat, and behavior.
The user can also manually input data, observations, and tidbits such as cultural influences.
As the people recording the information are children, their measurements may be inaccurate, and they may make wild claims and include myths and urban legends as facts.

Gather the data to fill an early Pokédex.
