i have both a crab and a turtle.  i like my turtle better, partly because i think turtles rock, and partly because my turtle does not use as much focus as a crab.  he is always able to use growl or bite.  a crab after 4 or 5 claws has no focus left.  don't go saying turtles are bad pets just because you don't like them.  i don't say cats are bad pets just because i don't like them.  there is no best pet and there is no worst pet(except for maybe the sporebat with no abilities, but i might be wrong on that as well,  i need more information on the account before i come to any conclustion).
