Diver earlier that morning played with her other sibblings for a bit. She noticed how her sister Ducky and brother Spike and their friends had adventures and went exploring. She decided to give it a try herself.
"Perhaps try something easy, explore and try to find Mr & Mrs Longneck, they are big, and should be easy to find them, yes it should." She said to herself as she paused for a moment.
She walked over to towards the edge of the valley wall, liking her exploring so far, munching on a leaf as she walked. "Now if I were a long neck where would I be. I will try over there, yes that will be good." She said as she continued walking.
She walked along getting a bit closer, "As long as I do not find that scary Mr threehorn, that would be bad, yes it would."
OOC: I got the char idea from the fact that some animation of Ducky's siblings look exactly like her, and from some lines in the family song in the movie where Spike leaves. How about at least one sister that looks exactly like Ducky, or very close. Though Ducky' & Spike's family can easily tell the difference their mother too of course. If he were present I'd assume Chomper could smell the difference. Not to silly of an idea I hope, and maybe be interesting. Her name comes from her liking to dive deep and liking the underwater green food a bit better then land food. I also thought the way Cera's dad acts it may make him scary to some kids around Ducky and Diver's age who had not been around him some like Ducky and the others had. Likely only her family would know of this since they'd hear her tell their mother of some of her scary sleep stories that had Mr Threehorn in them.
