When the Seafrog (or Frog) gets added along with new tar lakes, i feel like the seafrog should be able to sink in the tar if you’re not careful, and to get it out, you could craft a hand winch, lodge it into a nearby rock or structure, and slowly pull it out.
Later on, if the trident gets added, the devs could add a winch upgrade specifically for the trident, it is highly situational and if it was to be added, it would be at the end of Early access, but i also think that it should not be an upgrade module, but more like a physical attachment to clip onto the bottom of the trident, like the tadpole attachment system where you can put one item on the back of it, i think this would add a bit more dangerous.
If the grappling arm or another arm gets added, it should also allow for the seafrog to pull itself out of the tar.
Whole lot of qol additions here, but i think the tar pits should also have a depth system where some parts are deeper and others are shallow, and i believe that if the tar is shallow enough, the tadpole should be able to eject from the seafrog chassis, and maybe make it so you could attach the winch directly to the back of the seafrog and pull it out (if its shallow enough to eject).
And if its not, the tadpole system will play a voiceline telling you that you are stuck and need to exit, and also to not activate the thrusters, as it would be a punishing feature if when your stuck in tar deep enough for the thrusters/jets to be blocked, if you were to activate them the engine would overheat/shut down the oxygen support, meaning it would be crucial to bring a winch and a repair tool before accessing the tar lakes.
