“At home we have a digibird with a little cage, with a ribbon we put it up in the living room.
My 8 year old son, had already found all the hidden easter eggs this morning, apart from the one egg which we’ve hidden in the digibird cage. Only after a while and with lots of ‘warm/cold’ clues he found it!
