At one point during his recovery, Chito left the croc in a lake near his
house. But as he turned to walk away, to his amazement Poncho got out
of the water and began to follow him home. Chito recalls: "That
convinced me the crocodile could be tame." But when he first fearlessly
waded into the water with the giant reptile his family was so horrified
they couldn't bear to watch. So instead, he took to splashing around
with Poncho when they were asleep. Four years ago Chito showed some of
his tricks to friends, including getting the animal to close his eyes on
command, and they convinced him to go public with a show. Now he swims
and plays with Poncho as well as feeding him at the lake near his home
in the lowland tropical town of Sarapiqui. The odd couple have now
become a major tourist attraction, with several tour operators,
including Crocodile Adventures, taking visitors on touring cruises to
see the pair.
On the Crocodile Adventures website it describes
the spectacle as: "One of the most amazing things that no cruise ship
passenger will want to miss, the adventure show between the man and the
crocodile."
