Dandelions are an obstacle block in Chicken Scramble that first appear on Stage 28.
Unlike Haystacks, Dandelions are not a stacked obstacle, and performing a match above, below, left, or right of a Dandelion will remove it and free the tile. However, if no Dandelions are removed on a turn while there are still Dandelions on the board, a new one will appear above, below, left, or right of a random, existing one.
