Dwarf Red Bulborbs (アカコチャッピー, lit.: "Child Red Chappy") are small and common enemies in the Pikmin games. They were originally known as Dwarf Bulborbs (小チャッピー, lit.: "Small Chappy") in Pikmin until various subspecies with different colorations were discovered; they are called just that in Pikmin 3 as well. At the end of Pikmin it is known that they are not of the same species as the Spotty Bulborb, and in Pikmin 2, they are revealed to belong to the Breadbug family, not the Grub-dog family.

These enemies perfectly resemble Red Bulborbs in appearance, but are much smaller. Dwarf Red Bulborbs can be easily defeated by swarming them, or by throwing a single Pikmin directly on top of them. In Pikmin 2, if a leader throws a Purple Pikmin on it, it will remain attached while the creature falls. In the first game, bothering one will make it release a loud scream, waking up the nearest Spotty Bulborb. Dwarf bulborbs do scream in Pikmin 2, when a Pikmin is thrown onto its back, but the scream does absolutely nothing. They squeal when a leader or Pikmin bothers them in the second game, as do the other Dwarf Bulborbs and Dwarf Bulbears. If this creature is petrified in the Piklopedia, when it breaks out of the stone it runs around eating any thrown Pikpik carrots at a much greater speed than normal.

In the Cavern of Chaos, on sublevel 8, more than fifty of them can be found, along with two Gatling Groinks.

Dwarf Bulborbs have a far deeper-pitched cry in Pikmin 3. They no longer shriek loudly as they did in Pikmin 2 when killed, but instead emit a deep, throaty sound much like the Red Bulborbs in Pikmin 3 do. This change seems questionable, as their smaller larynx should indeed produce a higher-pitched sound than that of a Red Bulborb, as seen with Bulborb Larva.
