CINCINNATI (AP) — And Daddy makes three.

The father of the Cincinnati Zoo’s popular baby hippo Fiona has joined her and mother Bibi in their first time together as a trio.

Zoo officials say Fiona, Bibi and Henry were united in the Hippo Cove outdoor pool Tuesday morning before the zoo opened. They say the supervised visit of about an hour went well, with Bibi properly reacting protectively.

Fiona has been exploring the outdoor habitat with Bibi for several weeks, with some contact inside separately with Henry.

Fiona was born Jan. 24, weighing 29 pounds (13 kilograms). She overcame health scares and now weighs nearly 375 pounds (170 kilograms). Her parents weigh about 10 times that.

Video updates such as Fiona taking a bottle, splashing or running have drawn millions of online views.
