In Pikmin 3: The Dweevil's Revenge
In Pikmin 3: The Dweevil's Revenge, Blue Bulborbs have slightly more health, bite less often, and shake Pikmin off more. They have a blue backside with green spots and have what seems to be gills not unlike the ones Blue Pikmin have. Attack them as if they were any other bulborb. Because they have more health, however, Purple Pikmin should be used.

In Pikmin 3.9
In Pikmin 3.9, the Blue Bulborb is a semiaquatic grub-dog that looks like a Red Bulborb with a blue backside with white spots and a blue, -like tail. It walks around in search of prey either in or out of water, and while submerged it occasionally swims up to take a breath. Swarm its tail to prevent it from swimming away and to secure an easy kill.

In Pikmin Eco
The Blue Bulborb is a subspecies of grub-dog appearing in Pikmin Eco as a close relative to the Red Bulborb. It looks very similar to the Red Bulborb, except that it is blue in color instead of red, and always spawns in submerged areas. While having slightly more health, it's also slower than the Red Bulborb.

In Pikmin: Distant Planet
The Blue Bulborb is an aquatic close relative of the Red Bulborb and Yellow Bulborb in Pikmin: Distant Planet.

The Blue Bulborb is another supposed color of bulborb, and this creature is said to be blue depending on its native region while it may appear red or yellow in others. As with Red Bulborbs and Yellow Bulborbs, Blue Bulborbs also have a dwarf counterpart.

In Pikmin: Redemption
The Blue Bulborb is a relative of the Red Bulborb in Pikmin: Redemption that resides in water. It has blue skin, white spots, webbed feet, and gills.

In Pikmin: Wide World
The Blue Bulborb appears in Pikmin: Wide World as a semiaquatic grub-dog found exclusively in Balmy Highlands, as well as its caves, because of the area's clear, clean water. Its dwarf counterpart, the Dwarf Blue Bulborb, is frequently found somewhere close by. Blue Bulborbs can be host to parasitic Pikmin, causing the existence of Blue Bulbmin. Blue Bulborbs prefer to sleep in water that completely submerges their legs while they are standing, and may be found sleeping in a variety of positions. Their dwarf counterpart, however, prefers to hunt in more shallow water. A Blue Bulborb will awaken if it is touched, injured, or hears a sound loud enough to rouse it from its sleep. While it is awake, a Blue Bulborb will pursue any Pikmin and leaders in its sight, even traveling into deeper water to catch them, until they leave its territory. This will prompt the creature to find a spot to rest near the center of its territory and return to its slumber. The Green Bulbot is similar to the Blue Bulborb, but is mechanical and resides within acid instead.

Blue Bulborbs are the same size and shape as most other bulborbs but have a distinct appearance. They have tan skin, a blue backside with white spots, light green eyes with white sclerae, a pair of gills on either of their cheeks, and webbed feet. In its reddish mouth is a pink tongue.

Defeating a Blue Bulborb can be tricky, as they are always found sleeping in a body of water. Although they can be attacked most easily using Blue Pikmin, by charging them at the creatures' backside, swarming a sleeping Blue Bulborb with Winged Pikmin is also a viable strategy as they can fly over bodies of water. Caution must be exercised, however, to not allow Winged Pikmin to be thrown into the water after the creature shakes them off. A Blue Bulborb can also be led out of the water so that it may be attacked by land-faring Pikmin, although this can be dangerous because the creature will be ready to eat its prey. As with many grub-dogs, throwing Pikmin onto the creature's eyes will cause it to flinch, buying precious time to defeat it with little to no casualties, as well as inflicting damage and making it release any Pikmin currently in its mouth. Any leaders that end up in the creature's mouth will be chewed up, and then spat out alongside any Pikmin in its mouth at the time. Upon defeat, a Blue Bulborb will fall to the ground and yield. On the surface, its body can be carried to either the Master Onion for ten Pikmin seeds or the Dolphin Lander for. Underground, a Blue Bulborb's remains can be carried to the Lander Pod to either immediately gain or be saved for later to gain ten Pikmin seeds of any chosen discovered color from the Master Onion, but only if the cave is exited using an escape geyser.
