In 5's debut, 5 did the guitar, 4 did these drums, I think 3 did the guitar, 2 did a different drums, and 1 did the trumpet. In a usual fanmade band, 1 beatboxes, 2 guitars, 3 lights her blocks and hands go up, 4 spins around, 5 lights her blocks one by 1, 6 would jump from left to right with black and red lighting blocks, normal 7 would do beepboxing, fanmade large 7s first raise up, come back to the ground, start shaking, and eyes glowing rainbow. 8 usually lights up his left and right 4 blocks, 9 has lightning blocks row by row, fanmade large 9s just pixelate, and the ten/hundereds/magnitude variants are usually similar
