Kids who went to the Lincoln Children's Zoo on Sunday left with more than just memories of wild and exotic animals. They also learned about the importance of water safety.

"Josh the Baby Otter" is a book that Blake and Kathy Collingsworth wrote after their son Josh drowned last year. It promotes education for young children and babies to teach them to float if they ever find themselves in water. In addition to book readings, a larger-than-life Josh the Baby Otter also made an appearance to visit with kids at the zoo.

"We really want to get the word out there to teach your kids," Kathy Collingsworth said. "To get into some sort of swim program, whether it is at an infant level with the float for life classes that are now at the YMCA, or just getting the message out to the children."

This was all a part of Otter Day at the Zoo. People that attended were also able to meet a real otter caretaker and see feedings with the zoo's three otters, "RC", "ET" and "Hanz".
