Table of Contents
Crucial Pre-Game Preparation
Before you dive into the first chapter, you must understand a few critical rules that dictate your success. Unlike some games that demand multiple runs, you can complete all achievements in Reanimal in a single playthrough. The game features nine chapters in total. If you follow this route carefully, a full completion run will only take you about 3 hours. Many players ruin their runs by ignoring the specific rules regarding missable items.
The Danger of Missable Items
You absolutely must collect all Coffins and Hidden Statues in a single continuous playthrough. Gathering them via the Chapter Select menu will completely void your progress for the secret ending. If you try to use Chapter Select to pick up a missed Coffin, the game denies you the Secret Ending. If you use Chapter Select to grab a missed Hidden Statue, the final statue fails to activate. This consequence permanently locks you out of obtaining the Sheep Mask. If you miss even one of these crucial items, you must start a brand new game and collect them all over again.
Safely Using Chapter Select
You can safely collect the remaining items like Masks, Posters, Secrets, Critters, and Rest Points using the Chapter Select feature. To do this without ruining your save, start a New Game in an empty slot and replay from your desired chapter.
Farming the Lost at Sea Achievement
The Lost at Sea achievement requires you to travel a massive total distance of 10,000 in-game units using the boat. A standard completion run usually nets you around 6,000 units. Fortunately, your travel progress carries over across your different save files. Do not stress about finishing this immediately. Keep an eye on your achievement progress percentage while playing. Chapter 6 features the final story segment involving the boat. You can either drive in circles during Chapter 6 until the achievement unlocks, or simply start a New Game after you beat the story and drive the boat back and forth near the shore in Chapter 1 to farm the remaining distance.

Chapter 1: Dead in the Water
Before starting, take note of the Hidden among the pines achievement. You must locate all 19 secrets hidden across Chapters 1, 2, and 3 to unlock it. The Rest Your Legs couch and chair locations do not count toward this total.
Secret 1 (Mask 1 of 18)
As soon as you climb the initial ladder, a character shuts a gate directly in your face. Climb the wall located to the left of this gate. Ascend the next ladder and take an immediate left turn. Follow the path completely around the corner and step outside. Squeeze your character through the visible crack in the wall to discover your first mask inside a box.
Rest Your Legs 1 of 10
Shortly after collecting the first mask, you encounter a massive pipe that requires crossing. First, you must restore the power. Enter the small room housing the power switch. You will notice a comfortable chair right next to the computer. Sit in the chair to log your first rest point.
Secret 2 (Mask 2 of 18)
After you cross the massive pipe, you step into a locker room. Walk straight to the locker positioned directly opposite the main entrance. Open it and step inside to discover a hidden room. You will find the second mask hidden securely under the sink.
Achievement: Dark Tourism
You soon step back outside and climb another ladder. You will observe a man walking away into an alleyway. Stop immediately. Do not follow him yet. Walk past the two rails and turn the corner to find a hidden balcony featuring two chairs. Kick the chair holding the dummy down to the ground to unlock the Dark Tourism achievement.

Secret 5 (Mask 3 of 18)
From your current location, squeeze through the crack in the wall. Pick up the plunger lying next to the body. Use the plunger on the illuminated toilet in the center of the room to fish out a key. Take the key and return to the courtyard. Enter the second door (the one lacking a light above it). Follow the interior path to a room filled with explosives. You will find the third mask hidden beneath the table holding the bomb.

Secret 7 (Hidden Statue 1 of 5)
Return to the main tracks. Do not get back into the minecart. Follow the train tracks on foot until you reach the end of the tunnel. Look for a crack in the left wall. Squeeze through it to discover the first hidden statue. Interact with the statue to light its candle.
Secret 8 (Poster 3 of 20)
Later in the chapter, you engage in a tense chase sequence. Use the saw to clear your path and outrun the Hunter’s ice cream truck. Once you escape and jump down a small ledge, turn completely to the left. You will locate a camping trailer. Grab the poster pinned to the side of the trailer.
