Looking to complete your trinket collection in Mail Time? Bottle caps are one of the game’s most elusive collectibles, not tied to any quest, but essential for unlocking the Archeologist Patch, which requires finding 40 trinkets. These caps are easy to miss, cleverly hidden across Grumblewood Grove, and this guide will help you track down every last one.
Updated for Patch 1.0.6 (2025) Verified on PC and console versions.
Where to Find All Bottle Caps
There are 3 confirmed bottle caps in the full release of Mail Time. Each is tucked away in a high or hard-to-reach location, requiring gliding, mushroom bouncing, or creative platforming.
1. Grape Soda Bottle Cap
- Area: Treehouse near the swamp
- How to Get There:
- Start at the flower field
- Head toward the swamp entrance
- On your right, look for a large rock formation with a wooden walkway
- Follow the walkway and bounce up using mushroom ledges
- Enter the treehouse and find the cap just under the window, past the door
🧭 Pro Tip: Use the yellow mushrooms to bounce higher, they give more vertical lift than the red ones.
2. Honey-Drawn Bottle Cap
- Area: Fence post between the flower field and the farm
- How to Get There:
- Locate the well near the flower field
- Climb the well roof or the tall tree nearby
- Glide toward the middle fence post that separates the two zones
- The cap is sitting right on top of the post
🧭 Pro Tip: If you miss the glide, try launching from the wooden walkway between the picnic and bamboo areas for a better angle.
3. Berry Blast Bottle Cap
- Area: High branch near Max in the bamboo grove
- How to Get There:
- From Max’s location, head toward the cliff edge on the left
- Look for mushrooms growing on a large tree in the flower field
- Glide to the mushrooms, then jump around the tree to reach a wooden walkway
- Follow the walkway and use more mushrooms to reach the branch with the cap
🧭 Pro Tip: This is the trickiest one, use double jumps and glides in quick succession to avoid falling. If you fall, retrace from the flower field side. A breakdown of these three locations is shown in this Mail Time bottle cap walkthrough video.
Why Bottle Caps Matter
- They count toward the Archeologist Patch, which requires collecting 40 trinkets
- They’re not tied to any quest, making them easy to overlook
- They’re leftover Easter eggs from a removed side quest involving Irene and Donna in the demo version, according to the Steam discussion thread
- They’re undeliverable, but still collectible, think of them as hidden lore items
Completionist Tips
- Collect them early: You don’t need to wait for a quest to trigger
- Use the glider often: Most caps are in elevated or awkward spots
- Track your trinkets: Use the Patch menu to monitor progress toward the Archeologist badge. Details on overlapping trinkets and patch unlocks are also explained in the Mail Time guide on LadiesGamers
- Don’t confuse them with coins or gems: Bottle caps are flat, colorful, and usually found solo
Summary Table
| Bottle Cap | Area | Landmark | Method |

Bonus: Dev Trivia
According to Steam community discussions, the bottle caps were originally part of a cut love quest between Irene and Donna in the demo. While the quest was removed, the caps were left in as hidden collectibles, a subtle nod to early testers.
