one thing i have to say, this is just what the voices of Alex and his friends would be like

Alex: brave, a little shy, the voice similar to that of simba from the lion king

Kasey: friendly, a little playful, like the voice of yasiri from the lion guard

Jack: a little egocentric, with an adolescent tone, but also with a burlesque tone

Sarah: with the tone of a 5-year-old girl, like unikitty's voice, but with a teenage tone

Daisy: funny, with a teenage tone, with a voice type of summer from dragons rescue riders

Doggy: with the tone of a ten-year-old boy, like puppycorn from unikitty, and sometimes he just barks

Aurora: sweet, brave, with a burlesque tone on some occasions, like lillie from pokemon sun and moon

Sparky: with a voice with an almost adolescent tone, like the voice of cutter from dragons rescue riders
