Dr Big Mac aka Kekdu the Crab

Hi! I am Dr Big Mac aka Kekdu – buddy for little ones to treasure and perfect for pretend play or story telling time. In fact, I am loved by kids but often scare the adults! 🙂
Some FUN Facts about Kekdu

2. Crabs are decapods (ten footed) from the crustacean family however, first pair are claws known as ‘chelae’. Some crab species can naturally autotomise (shed) limbs such as their claws, which then regenerate after about a year
