Lyrics
''I could get used to this heat on my skin I can feel every day, I'm a little bit stronger I only wish each day was longer

Yeah! We're having fun in the sun (the Alolan sun) Week after week It's just like we're on vacation

Yeah! Now our journey's begun, Friends 'til the end Number one's our destination

Under the Alolan sun Pokémon!''
