Brennan on zapsai

Right after the events of paleonerds endgame, Brennan had a mission to go to zapsai where he will hide the jehovah gold from preying thieves
on the planets atmosphere, he sees a big blue sky with giant flying whales and white clouds. while enjoying the view a giant whale mistook the ship for ship for a large air shrimp and rammed straight into it
the ship plummeted into a deserted island without a trace. brennan is undamaged due to his symbiote but the paleonerds beacon is destroyed and the ships engine is unsalvagable. his GPS is at 20 percent battery but he knows where he is
after sitting on his broken ship and thinking what to do he remembered the villager on the planet who will be coming back to zapsai after endgame. unfortunately his island is on the opposite side of the planet and with no ship, he cannot do anything about going there.
he soon begins to venture this island following the estuary to seek materials to build a tent.
DAY1-
brennan ventures deep in the temperate forest at sunset while feeling as if a thousand eyes are looking straight into his soul. he finds tinderwood which is quite brittle and some tree sap for glue. all he needs now is some sort of fibre
at night brennan finds rhe remains of a dead flying whale and as tragic as it is he simply tears the wings out as cover for his tent
DAY 2- stampeding giant snapping turtles trash his tent and lay waste to his food as he slept. he immediately finds a cave just on a hill to the north of his tent. fortunately the cave is uninhabited and will do good for the day. brennan now marks the cave and heads downwards to a small stream to catch small aquatic animals to eat. 
after catching a couple of fish brennan decides to gather some grass as vegetables. when headed back to the cave he sees a giant feather in the enterance leaving him to wonder what is inside. 
he abandons the cave and spends to whole night walking upriver.
