Lie down on the ground and crawl in circles until you stumble upon the spear.
Use your cape as a bandage, also as a guard around your hands, like armor. Continue to crawl in circles.
Now that your spear is located, you seemed to remember where your shield was (beside your spear) and located your shield.
Now that you have those, fell around in your inventory to get that lint from earlier( when you shoved hippo in hole). Use the acid that somehow helps eyes, by putting it on your lint, and gently tapping into your eyes.
