Chapter 1: The Mandalorian - S1-E1
Plot hole: Nick Nolte's little guy is supposedly terribly helpful towards Mando, showing him "the only way" to reach the enemy encampment, which is by riding the weird fishy beast, but when Mando surveys the target and the robot reveals itself, you can see that there are only shallow hills around the base, a large clear path of land, nobody even is on lookout...and most importantly, in the following episode, Mando makes it back on foot anyway, no blurrgs - and evidently the baddies had no vehicles, making them even less of a threat to begin with. And for being so helpful and good natured, he did not tell him to park the ship by/at his place nor warned him about the Jawas.
Chosen answer: They could be just like wrinkles from age, like the elderly Togruta in the Zygerrian slaver arc in The Clone Wars series, as Ahsoka is considerably older than her animated appearances. I think there is probably a character design/stylisation aspect to it as well - the other Togruta we've seen in live action, Shaak Ti, has four segments or folds in her lekku that were not visible in her Clone Wars appearances, so it would seem the character design in Clone Wars and Rebels reduces such features.
