Mon-chan sure is a handy gal. Her lil mechanic suit is adorbs!!!
Did you know? Most octopi are quite fast! Some are even fast on land, though "fast" on land is relative. They have a rather unwieldy gait on land which allows for lurching speed. In the water, it's a completely different story! Octopi typically swim by boosting through the water with a system of valves which push seawater out through "vents", and that gives them repeated bursts of speed, especially when they take off from the ocean floor! I should note that they prefer to avoid straight up chases however. Most of their predators are usually just straight up faster than they are, which is why they rely on camo and their ability to squeeze into super tight spaces to avoid predation... Or in the case of Blue Rings, their toxic bites and poisonous flesh.
Another fun fact is some species take a different approach to avoiding predators. Mimic Octopi, for instance, are capable of mimicking the shapes and movements of other animals! They've been known to mimic frogfish and lion fish, as well as stingrays!
