Numbers are easy to read and hard to picture. In Size It Up you drag a mystery object until it looks right next to a reference drawn at true scale, then the reveal shows how close you came. Bergmite turns up in the daily puzzle at random, and the Pokémon practice set deals five Pokémon at a time.
Measurements are the canon figures listed on the Pokémon Wiki (Fandom) page for Bergmite ↗. Where a character has several forms, the size above is for the form shown in the artwork.
