So they were going to rebuild their homeworld with like 30 people? There have to be way more Mandalorians out there somewhere, right? At least Boba and Sabine for starters.
The one thing is this part of the plot moved way too quickly. They just defeated the pirates and Karga gifted them some land in Nevarro to settle but they are already set to go back Mandalore. And they kept talking about taking Mandalore back. From who? It seemed like pretty much a "dead" world without much activity from their visits (yes, there were many species they saw, but it didn't look like the planet was occupied by any means). Has Moff Gideon been using Mandalore as a base all this time? Apparently so.
I guess that wasn’t the Mythosaur that erupted out of the ground but I sure thought it was going to be.
No, but it seemed weird that the creature destroys their skiff/hovercraft and the Mandalorians go to this cave that conveniently leads them to the Great Forge. Like, "Oh yeah, we've arrived at the Great Forge. Too bad the valet took out our means of transportation."
