The Marrow Flea Location

Overworld View Map Location
The Marrow Location
The Marrow Flea

One of the lost Fleas are located in The Marrows, on the very top of the area which is initially unscouted by the map until you save your progress. This section is a platforming area with multiple obstacles and opposing bugs blocking your way.

The Flea itself is located on the top right of that area, requiring you to break it free from entanglement. Make sure to approach it afterwards so it can fly and leave off the map.

Requires Platforming to Approach

The Flea located in The Marrow requires the player to go through a platforming segment that will make them go around the top right corner of the map. Simply follow the road and constantly head upwards to reach the Flea's location.

Beginner's Guide: Tips and Tricks

Deep Docks Flea 1st Location

Overworld View Map Location
Deep Docks Flea Location
Deep Docks Flea

There is a Flea located on the lower part of the map of Deep Docks, requiring you to break a secret wall from the Bell Beast Station to the left while traversing the waterfall lava section.

This Flea is already initially visible to you once you enter the map and once you collect it, a nearby platform will break, allowing you to fall down to the start and leave the area quickly.

Avoid the Falling Lava

The main platforming challenge for this Flea is to avoid the timed lava waterfalls that have different intervals. Just remember that the middle lava waterfall is fast and the leftmost one requires some long platform jumps.

Deep Docks Flea 2nd Location

Overworld View Map Location
Deep Docks 2 Location
Deep Docks 2 Flea

There is a 2nd Flea in Deep Docks located on its upper section, initially unavailable to the player due to the lack of a jumping aid that allows them to close the distances between the far platforms.

The player may initially ignore this section, but remember the location for backtracking later as you will unlock the gadget required after exploring the lower portions of Deep Docks.

Use Swift Step to Dash and Reach Platforms

Once you have explored Deep Docks and unlocked Swift Step, you will have the ability to dash jump through the platforms you might have visited earlier. Go to the topmost section of the area and activate your dash to get through the platforms until you see a lever.

Strike the lever to lower a counterweight that you can climb on and continue heading above until you find the Flea.

How to Unlock Dash

Deep Docks Flea 3rd Location
