Pandora differentiates herself from Grizzo both in lovely pink colour and by the shape of her ears. Her voice is softer than Grizzo's.
She's a little shy and quieter than Grizzo, but she's actually also a passionate rock-and-roller! She's not as outgoing as Grizzo, and is more at home among high-rise buildings and urban landscape than her green girlfriend. She spent a lot of her life with her musician father living in a nice dark cave.
Greta is a halloween-themed Grizzo, adorned with a grey witchy hat and a cloak, and stripy black-and-orange legs. Her speech always sounds a little bit like a friendly witchy giggle.
She describes herself as Grizzo's aunt, but it's not clear if this is a biological relation or a platonic term of endearment. Nevertheless, she watches over the two young lovers.
