Unknown Craft in TPM DVD extras!?! What is it???

(I don't know if this question has been asked yet or not)

My friend and I were watching TPM dvd extras and saw a ship or craft that niether of us had ever seen. On the extras DVD: go to "Deleted Scenes and Documentaries" then go to "Deleted Scenes Only", then go to the last deleted scene titled "Farewell to Jira". At the end of that scene, right after Qui-gon says "Not like anything I've seen before, Come on" to Anakin, the camera follows them then pans to the right revealing a large craft with three legs, that look an awful lot like those of an AT-TE walker. We were hoping that someone could shed some light on this unusual craft, perhaps the name of it and which end is the front. Thanks
