We were right all along, and Series 6 of Numberblocks is gonna premiere on 4th March. I can't imagine how much dym cids are gonna explode once seeing this... Rest in peace my late 2022-2023 fanmades, you had such a good run with me. Nearly to 500, did much better than my early 2022 fanmades, (So far, up to Yellow Level 3 NBs have confirmed to appear (The first 10 episodes appear to be OL2). We need to wait until the Green Level 4 episodes come, which'll definitely be in the second half of S6, to see if any new numbers are joining the cast of colourful Numberblocks.)
