Well. I admit I’m not entirely certain how best to advise you here, as “acting up” for a wobbuffet can mean a wide variety of things, ranging from its usual lethargy to mating season. Does your wobbuffet sway back and forth and emit cries that sound eerily like Tom Jones’s “It’s Not Unusual”? If not, then at the very least, we can rule out mating season. Otherwise:
Wynaut The Bright Pokémon Type: Psychic Official Registration #: 360 Entry: A small, doll-like pokémon best known for three things: its constant smile, its habit of pushing up against solid objects and other wynaut in order to build strength, and its adoration of sweet fruit. The term “bright” pokémon is additionally a bit misleading. To put it in brief, the other thing wynaut is known for is its cry; to people of certain languages, it sounds like a phrase that can be translated into, “Really?”—which in turn has been interpreted as the concept of questioning and meditating on all that is. That, combined with its perpetual smile, its penchant for expressing “affection,” and all the other aforementioned traits, have led certain cultures to view this pokémon as a philosophical ideal—and thus, the incarnation of a vastly sage guru. In truth, wynaut are not particularly bright pokémon at all. Rather, because of their love for sweet fruits, they have a tendency to consume vast quantities of overripe and fermenting berries, and thus, their serene, sage-like behavior is better attributed to a state of perpetual drunkenness.
Wobbuffet The Patient Pokémon Type: Psychic Official Registration #: 202 Entry: The evolved form of wynaut, via battle experience. The blue portion of wobbuffet’s body, while containing a brain and several vital organs, is actually mostly hollow, balloon-like, and highly resistant to damage. (It is, in fact, quite true that the brain of a wobbuffet is actually located in its nerve-packed tail.) Wobbuffet use this to their advantage, as their entire battle strategy involves inflating their blue, balloon-like bodies, taking hits, and retaliating with psi blasts equal to double the amount of damage they endure. As wobbuffet are docile and will refuse to attack unless their opponent attacks first and as wobbuffet’s primary ability prevents them from leaving a battle once it begins, two wobbuffet facing off against one another will tenaciously stand and wait until their opponent passes out from starvation. It is for this reason that trainers who keep wobbuffet should be warned that intentionally attempting to battle another trainer’s wobbuffet is an easy and fantastic way to lose your trainer’s license.
Swaying along to Tom Jones, eh?
So then these are images of the wobbuffet’s mating dance in action, right, Bill?
Ah, it must have taken you days of traversing through cave systems to capture such beautiful images of the wobbuffet mating dance. Well done! Behold this technique, readers. Observe how enthusiastically this shiny wobbuffet dances. Clearly, he is desperate for a mate. Perhaps the females of his specific cave system are particularly selective, or perhaps his outer covering is not quite flashy enough. Don’t lose hope, noble wobbuffet! Someday, you, too, will find the female wobbuffet of your dreams!
