An elephant's trunk is it's nose. Elephants use their trunk to drink water as well.

Elephants have long trunks so the can pluck grasses and other food from the ground with having to bend down. The trunk also allows them to drink without bending over. They also use their trunks like hands for a vast number of tasks.
Elephants have long trunks for many reasons, but one of the most important reasons is so when they suck in water they can reach spots of their body to wash.
The elephant uses its trunk so that he/she can reach up into trees and get leaves. They also use their trunks to bath by sucking up water and splashing it all over itself.
