Ninja Squid

Users of Ninja Squid leave no trace while swimming on horizontal surfaces and ramps. However, swim speed is reduced slightly. This ability is restricted to clothing as a main ability and cannot be gained as a sub ability.

In-Depth Ability
With Ninja Squid equiped, the player does not leave ripples while swimming in Ink. However, ripples will still be visible when swimming up vertical surfaces. The slight indents left in Ink by swimming through it are likewise not hidden, allowing very perceptive enemies to still take notice of the player's presence. Base swim speed is also decreased by approximately 10%, though this can be mitigated with Swim Speed Up.

Use
Ninja Squid is used to move around the battlefield undetected. Because there are no ripples for enemies to spot while the player swims, they can sneak to a better vantage point or escape a dangerous enemy, such as a Kraken user.

However, the effects of Ninja Squid can be simulated simply by swimming slower, as ripples are only produced when swimming at top speed.

Mutual exclusivity
Since this ability is found as the main ability only on clothing, other abilities found only on clothing are mutually exclusive with it; in other words you cannot have them together. These abilities are cold blooded, Recon, and haunt. In addition, since wearing the Splatfest Tee is mandatory during a Splatfest, these abilities cannot be used for the duration of those events.
