If you put in "Druid" and "Level 23" you'll get ... the various animals in East Karana, crocodiles in the Oasis, a frogolok for a quest in Misty Thicket, gargoyles in Ocean of Tears, and finally elephants in South Karana. The froglok has a very detailed entry, and the gargoyles even have their own separate guide entry.
All of those, except the froglok and the gargoyles, are charmable animals (and the froglok/gargoyles can be killed by a Druid without charming).
