Numberblobs are characters in Numberblocks that are known to debut in their titular episode.
They are voiced by David Holt, Marcel McCalla, Emma Tate, Beth Chalmers and Teresa Gallagher.
Appearance[]

One with her Numberblob.
Numberblobs are spherical creatures that come in the Numberblocks' colours. They resemble small, puppet-like balls with no visible limbs at all. They usually change colour depending on the how many are in their group exactly as to the colours of the respective Numberblock. Except, instead of getting borders, they get a different colour for their lips (for example, for a Numberblob group of 10, those Numberblobs will be white with red lips instead of red borders).

Decablobs[]
Decablobs are a species of Numberblob that are ten times larger than normal ones. They are voiced by David Holt and Marcel McCalla.
Appearance[]
They are larger variations of the Numberblobs. As a Decablob represents multiplication by ten, it cannot be of any colour except white (at least so far), which is Ten's main body colour, or the pastel/greyscale values associated with Twenty through Ninety. Its lips and eyelids will be outlined in the darker colour that "frames" individual cubes on the equivalent Numberblock.

Trivia[]
Numberblobs[]
- The Numberblobs are similar to the buddy blocks from Numberjacks and possibly Alphablocks.
- Red Numberblobs have the most appearances.
- The Numberblobs resemble Pac-Man, but only when they're yellow in color.
- The Numberblobs usually appear as a background character that acts like an audience.
- Since Series 6, the Numberblobs have a subtle design change; they have reflections on their pupils for unknown reasons.
- Numberblobs are comfirmed to appear in every review of every multiple of 10, in/after Series 6. As of right now, The review of 1-10 is Numberblobs, and the review of 1-20 is I Can Count to Twenty.
- Unlike the Numberblocks' lip-sync mouth shapes, which are complex in various ways, the Numberblobs' lip-sync mouth shapes are simply closed for consonants and open for vowels, with the mouth opening and closing per every syllable, similar to a puppet.
- When the Numberblob was first seen in a teaser screenshot for the Numberblobs' episode, fans speculated that it was Zero and that it was red and round. This would be proven incorrect.
- The Numberblobs' style are based on a Muppet character.
Decablobs[]
- The name comes from "deca" (derived from "deka" meaning "ten" in Greek) and "blob", the latter word comes from the Numberblobs themselves.
- Judging by their name, they are probably ten Numberblobs combined.
- They are currently one-time characters, only appearing in Rockets and Rekenreks.
