Greta just loves to collect junk, especially metal junk - rusty cans, shiny tins, bent spoons, blunt knives, old pots and even older pans. Greta has the full contents of great Grandfathers' toolbox and all of great Grandma's metal hair curlers.
Her mum, an environmentalist who is busy saving the local park, calls her "Greta the greenie", but her father, a tidy man, thinks it was more like "Greta the garbo". And when mum sees the metal still-life Greta builds on the dining table, it's "Greta the genius"!
At last "Greta the good" is instrumental in saving the park and there she installs an amazing metal tower sculpture for everyone to enjoy.
