Human parents in Alola often warn their angry children that if they don't put their feelings behind them, their face will be stuck that way – and the children believe them, for they can point to the Toucannon flying overhead as proof. Toucannon parents, for their part, give no similar warnings about happy faces to their Pikipek chicks; they let them enjoy their youth while they can. For Toucannon regrettably know that when their children finish evolving, life will leave them every bit as frustrated as their parents.

Humans have often tried to discover the source of Toucannon's fury, but all of their theories suffered fatal flaws. Environmentalists ascribe Toucannon's anger to the changes humans wreaked upon their habitat, but Toucannon are one of the few pokemon to actually expand their range as a result of human activity. Many trainers believe them to be frustrated at being "weak" pokemon, but the burning rage which sets their beaks aflame saw some elite trainers adopt them, and no amount of victories calmed the anger at the source of these Toucannon's power. A few scientists even proposed that Toucannon were not annoyed at all, but only look that way to human eyes; if so, others retorted, why do Pikipek and Trumbeak make Toucannon faces when annoyed?

What annoys Toucannon, as far as anyone can tell, is life itself – or at the very least, the myriad of failures and disappointments in the experiences of every living creature. But while most humans can shrug them off well enough to remember the good times, Toucannon can not claim the same. They live on only to impart advice to younger pokemon, so they can avoid following their path, and perish when they can endure it no longer – at times, after living hundreds of years!
