Headscratchers / Dragonball Evolution

• Why did they spend hours in a hole when Roshi had superhuman jumping powers?
  • Because Roshi would rather spend the time explaining King Piccolo's backstory to Bulma. Once he's done, Goku has no issue jumping up to Yamcha.
• Why is Goku bullied for his name ("Geeko") but Chi-chi McRoberts isn't? She also has an unconventional name.
• Why isn't Goku seen as one of the "cool" kids? Despite being a bit of an idiot, he's a badass martial artist and conventionally attractive.
