Big Walk Yellow Tower Solution & Unlock Tunnels (Big Tunnel Trophy)

Players can enter the big tunnels that are initially locked by completing the Yellow Tower in Big Walk, which not only unlocks the Big Tunnels achievement but also unlocks a subterranean way to explore the map quickly. While players can technically go towards the Yellow Tower first after completing the starting area, they'll naturally come across the tower after completing the Blue Tower. Here's a complete guide on how to find all five gourds required to complete the Yellow Tower key puzzle in Big Walk and enter the big tunnels to unlock the trophy.
