Bidoof

The Plump Mouse Pokémon has the appearance of a sturdy rodent inspired by a beaver, with incisors that never stop growing. It uses them to gnaw on logs and rocks and keep them sharp. It lives near water and builds its nests in the surrounding area, although its activity can also lead it to nibble on whatever it finds in its path.

Pokédex entries describe it as having nerves of steel: nothing seems to disturb it, and it moves with more agility than its low, compact body would suggest. Its Normal type suits a land-dwelling creature without any marked elemental traits, while its quadrupedal form and brown colouring reinforce its riverbank-rodent design.

It occupies the first place in a two-species evolutionary line. At level 15, it evolves into Bibarel, which retains the beaver base and expands its capabilities with the Water type.

In battle, Bidoof has very little room to work with. Its HP is 59, but its defensive figures are 40 in Defense and 40 in Special Defense; Attack is only 45, Special Attack is 35 and Speed is 31. Its base stat total is 250, so direct exchanges usually go badly and any opponent with better numbers easily outperforms it.

Simple is the Ability that gives it a recognisable plan: it doubles stat changes. An Attack or Defense boost quickly becomes more valuable, although reductions are doubled as well. Swords Dance fits that effect and allows it to prepare a physical attack; Double-Edge provides power at the cost of recoil damage, while Crunch covers opponents resistant to the Normal type. Unaware offers a defensive alternative by ignoring the opponent's stat boosts.

The Normal type gives it immunity to the Ghost type, but leaves it with a single weakness, Fighting, and provides no resistances. Moody has a much more volatile effect: it raises one stat sharply but lowers another. It has been studied in Little Cup for its Abilities, especially Simple, but outside that environment it is not a common competitive choice. In a normal playthrough, it works better as a temporary attacker before evolving.

Bidoof belongs to the Water 1 and Field Egg Groups. Its gender ratio is split 50 % between females and males, so breeding it does not require an exceptional search for specimens of a particular sex. Its eggs hatch in 15 cycles, equivalent to approximately 4080 steps using the usual egg-cycle conversion.

Its most practically useful Egg Moves are Aqua Tail, Quick Attack and Superpower, which expand its physical options; Rollout and Double-Edge also provide offensive alternatives, while Defense Curl and Iron Head have more specific uses. In an adventure, its progression is straightforward: it evolves into Bibarel when it reaches level 15.

The species is associated with areas near water and its catch rate is 255. That figure represents a very easy catch, appropriate for an early and common Pokémon. Its growth rate is Medium and its base friendship is 70, two values that favour adding it to the team quickly from the very beginning.
