Can we call them painthorses?
As a teenager, Ambrosia used to feel a bit self-conscious over not being able to carry or pull as much as her cousin, and Zap was a bit too oblivious to realise that and joked too much about it. But eventually Amber was able to get over it and accept that all she could do was her best. After being told of this, Zap nowadays also often interminges her teasing with comments over how much she really does appreciate Ambrosia’s work and company.
It also helps her in convincing Amber to get her stuff down before it rains.
