Knock, knock, knock! Who is hiding behind the barn door? This cleverly designed lock board illustrates the daily life of farm animals and their young. It consists of 5 doors with different opening systems: a key (with padlock), a bolt, a chain lock, a toggle latch and a (button) lock. Each door is represented by a different colour and a different number and surprise, this number is equal to the number of baby animals hidden behind the door. This attractive wooden toy allows your child to develop their dexterity whilst learning colours, numbers and animals.
