Digimon Story Time Stranger Otamamon Field Guide

Otamamon Overview (In-Game Profile)
A larval Digimon whose epidermis has yet to solidify due to it living underwater. Otamamon swims through swamps and rivers upstream of the Net Ocean using its large tail, occasionally clambering onto rocks with its developed forelimbs to do vocal exercises.
Unlike those of an average organism, its hind legs are almost completely undeveloped, acting as rudders in the stead of its propulsive tail. Unlike other Rookies, this Digimon’s future Digivolution seems quite promising, but it’s extremely prone to mutation, so caution is warranted when raising it. Otamamon’s special move is Lullaby Bubble, which sends opponents into an eternal slumber.

Otamamon Digivolution

Digivolution is the process that allows your Digimon to grow stronger and unlock new forms. Each Digivolution path has specific requirements, such as reaching a certain level, achieving a minimum stat threshold, or meeting personality and bond conditions.
Some Digimon also require special items or story progression to evolve. Choosing when and how to Digivolve is essential, since certain evolutions may branch into multiple options, giving you flexibility in shaping your partner’s role in battle.
De-Digivolution
In Digimon Story Time Stranger, de-digivolution allows you to return a Digimon to a previous form. Unlike standard digivolution, which requires stat thresholds and level milestones, de-digivolution has its own conditions. To de-digivolve a Digimon, one of the following requirements must be met:
- Encounter requirement: The Target Digimon must have already been encountered at least once during your playthrough.
- Personality requirement: The Target Digimon’s base Personality must match the current Digimon’s Personality.
Meeting either condition will unlock the option to de-digivolve, giving you more flexibility in reshaping your team and experimenting with different evolutionary paths.
Otamamon can de-digivolve into the following forms:
