Not giving me much to work with here.
I’ll just say a little about Boga then, shall I?
First off, Boga is the name of the creature, not the species. I had that confused for a long time. I thought Obi-Wan was riding a Boga, as opposed to just Boga. Her name is Boga and she is a varactyl that is native to Utapau.
If you own the DVD versions (not blu-ray) of the OT, you’ll notice that Lucas tinkered with Obi-Wan’s scream towards the Sand People to have it more closely imitate Boga’s noise in ROTS. This is not confirmed but I SWEAR that’s the case.
Her actual sound/voice in ROTS was made from the sounds of a Tasmanian Devil, dog, and coyote. Funny that they put a distinctly canine sound with a reptile…
The name of Boga comes from a soda that the crew drank while filming ANH in Tunisia.

The chase begins. Obi-Wan drops his lightsaber while riding Boga.
