You're not supposed to play around it, it's meant to make you lose. But don't worry, The Angler will only play the bear wall on your first run through or two to prevent the player from progressing too quickly. Once you find the Stinkbug and the Knife, he shouldn't summon them anymore and you can progress past him. Make sure you're taking time to look around the room for puzzles/secrets.
