Ob-La-Di, Ob-La-Da

Each Ob-La-Di, Ob-La-Da looks like a small, flat, round disc resembling a cookie, with six stubs protruding from its edges. It visually has a four-toed paw print on its back. When duplicated, the bodies seem to link together via their stubs. Akefu calls Ob-La-Di, Ob-La-Da an insect but notes that its species aren't technically insects, as they lack a three-segmented body or jointed legs.↗↗

Ob-La-Di, Ob-La-Da is a parasitic Rock Organism, as it feasts on other organisms' blood and bodily fluids. It is shown to be virtually motionless, only moving whenever attacking or being attacked. It is shown to protect its master, Wonder of U, and it can be inferred that it is subservient to Toru. Ob-La-Di, Ob-La-Da's species target any animal from above or below.↗↗↗

Ob-La-Di, Ob-La-Da is afraid of water, as it prefers to live in dry areas and is shown to shriek whenever it's submerged underwater. As a Rock Organism, it also hates storms and rising waters.↗↗↗↗

Despite its small size, the organism is shown to be relatively strong enough to deflect a soap bubble shot by Soft & Wet at a high speed.↗

Latching

Ob-La-Di, Ob-La-Da can latch itself onto its victims, like a tick, via a highly sticky substance secreted from its underside. This is effective for the Rock Organism to burrow into the victim's skin and absorb their essence. This creature inhabits a cliff in the wilderness and jumps down on other animals passing beneath it. Once latched, it sucks the body fluids and blood of its victim.↗↗

Body Replication

Ob-La-Di, Ob-La-Da can spawn copies of itself at a rapid pace from its victim's blood to the point of overwhelming its victim within seconds. Attempting to attack or pull off one of the pads spawns more of its bodies, proving any attack against it seemingly futile. When the body multiplies, its copies form out of one of its stubs.↗↗
