Two Bulborb subspecies are known to have been cut from the final versions of the Pikmin games. Both colors match those of the three main Pikmin types. Along with the Red Bulborb, each basic Pikmin type would have a fitting Bulborb had these not been removed.
Blue Bulborb

It is clearly a Bulborb with white spots; it apparently acts like the Dwarf Red Bulborb, with the same health, attacks and weight. An adult version was never shown.

Yellow Bulborbs appeared in the same video as the blue one. A dwarf version was also seen. These could have been later redesigned to Orange Bulborbs.
