At the hot spring, the Mandalorian is seen taking many eggs out of the water to put into the pack, yet the number of eggs in the pack itself seems never to increase, and sometimes even decreases. It is doubtful that he himself is eating them.
After the small assailant is launched into the air holding onto Mando's jet pack, the Child's mouth is open in amazement during the closeup side view, is closed during the close up front, and open again in the side view.
When the ship takes off from the ice planet, the dead large spider's leg is seen limply laying across the ship and easily flopping out of the way as the ship takes off. Spiders effectively have hydraulic skeletons; the leg's natural relaxed state is bent, and requires fluid to be forced into the leg to push the leg outward into a straight position. The legs of a dead spider would never be extended in a loose and flaccid way. Hence why dead spiders are seen to curl up when they die.
The Mandalorian cannot use hyperspace for his trip and so goes to another star using 'sublight'. But if this means 'slower than light', the trip would take years.
