Goofs

(at around 37 mins) when the Tusken raider kneels in front of the dragon's cave, his weapon is in his right hand as he deposits it on the sand; in the next shot, the weapon is standing up and in the left hand. Finally, in the next cut, as he stands up, he picks up the weapon from the ground with his right hand again.

The final detonation's depicted blast wave does not seem to affect the surrounding attackers.

Anything the size of the Krayt dragon moving through the ground that close to the surface would leave behind a significant trench.

Cobb Vanth rides a land speeder clearly powered by a turbine. Turbine engines operate by sucking in air at a high rate of speed and combining it with fuel. Sand, which Tatooine has in plenty, would down wear the engine rapidly.

Given that Podracing is a time-honored and iconic tradition on Tatooine, it would be logical to assume engineers like Anakin put measures in place to deal with this.

Tatooine has 2 suns. Only one shadow is cast during all outdoor scenes. This is an homage to the well-known and well-documented goof in A New Hope.

Each time "The Marshal" travels on his speeder, his hair does not move in relation to the higher velocities.

Cobb Vanth is able to tell Din Djarin his backstory while they are travelling at high speed on separate speeders. The sound of his voice would not carry over the engines or the wind.

When the Tuskans are formulating a plan using a snake skeleton and small rocks to represent the dragon and Tuskans, Cobb Vanth states that the scale is off, arguing that their depiction of the dragon is too big, though Mando and the Tuskans confirm that the scale is accurate. The rocks should actually be much smaller in proportion to the skeleton, given how large the dragon is depicted as being when shown.

When the Mandalorian is describing the deal with the sand people for the townspeople's help in killing the krayt, he says they want the it's carcass and it's ichor, mispronouncing the word. It's "eye-kor".
