The WOOPIE brand farm puzzle , part of the GREEN series , is a creative alternative to classic puzzles and blocks. Colorful, illustrated cubes allow children to combine learning with play, while wooden animal figures introduce role-playing games and farm life. Each cube depicts a different house – from a large cow to a small chicken – numbered according to the size and number of animals. The pictures depict English names , helping to learn languages ​​from an early age.
