The Orange Bulborb is an enemy in Pikmin 2. It has a general Bulborb appearance, but has black skin, yellow bloodshot eyes, and its backside is orange with black spots. The total effect makes it look somewhat like a discoloured ladybug. It has the same strategy that all Bulborbs use for attacking; however, this is a unique Bulborb that has a wider range than other Grub-Dogs. It will wake up when a captain ventures within Pikmin throwing range of it. The Orange Bulborb has slightly more health, making it difficult to defeat with the traditional Bulborb-defeating tactics. It is otherwise the same as the other Bulborbs. They may be found in many places, such as the Bulblax Kingdom, or in the Wistful Wild by the Dream Den. Usually when there is one of these around, it is almost guaranteed that there will be a few Dwarf Orange Bulborbs near it.
Note: The following part(s) of the article is a strategy (or strategies); therefore, it is highly subjective, meaning it may not work for everyone.
If a large group of Purple Pikmin is available, simply rain them down on the Orange Bulborb's back. Even with the Bulborb's head start, the Purples will have a good chance of stunning it with serious damage, and usually defeating it without any losses.
Orange Bulborbs are tricky without Purples. It is never wise to attack a large grub-dog from the front since they will almost surely bite back, and since the Orange Bulborb will wake up before it can be attacked, it tends to be highly troublesome. If it is approached from the back, quickly run and rain Pikmin on it. It can then be defeated like any other Bulborb. If there is no choice but to approach it from the front, dismiss the Pikmin (in a safe place) and use a captain to wake it up. Let the Bulborb chase him until he runs out of its range. When it falls back to sleep, return to the creatures back and release an attack. Orange Bulborbs also have a slight delay in between their "yawning" sequence and waking up again, so use this opportunity to pummel it with Pikmin.
- The Orange Bulborb's scientific name translates to "eye kageyamii orange".
