Hello!
These happy chaps are a range of seed packets designed to fold out and grow!
They'd be sold to children in newsagents like Pokemon cards as an alternative to sweets and as a little gardening projects to encourage environmental awareness.
Basically there'd be some sort of compact soil within the character and then you just add water, let it grow and then plant the whole thing in the garden or a big pot!
Suspiciously carroty looking cress...
