Estava no original
Como você disse, essa é uma worrt .
Worrts are brown, chuba-like creatures with toothy mouths that made their home in the desert wastelands of Tatooine. They would use their long tongues to capture unsuspecting prey as it passed, mostly insects and rodents. Perhaps the most notable worrt in the galaxy lived on the road to Jabba’s Palace in the Dune Sea.
Estava no original e não era CGI. De acordo com o Banco de dados de Star Wars :
The worrt was a puppet, like many of the creatures seen at Jabba's palace in Return of the Jedi. Its production nickname is simply "road creature."
Aqui está uma foto do fantoche, de alguém que parece ter participou de um show de prop.
