Luke's Hav-attack

Luke is so busy keeping up with his cousins this week. Both of them have tanks or containers where they keep the creatures they find on the beach or in the canal: crabs, shrimp, fish. They call these their habitats - but Luke doesn't understand. He calls his wagon full of water and creatures a "hav-attack". We try to tell him it's a HABITAT. He disagrees that this is because "first you attack your animal and then you have him so it's a Hav-Attack"!
