  • Alicia appears with her brother Diego in the Dora and Friends episode, "For the Birds".
  • Alicia is usually thought of as being Diego's only sibling, but Alicia is actually the middle child, as the oldest of Mark and Melanie's children is Daisy. However, Daisy is way more remembered and shown in Dora the Explorer, so Daisy is often forgotten.
