Thorny flower

Spiky Plants are strange, round plants with red spikes seen in Super Mario Galaxy and Super Mario Galaxy 2. They come in a normal size and a huge size. They hurt Mario/Luigi when touched, so the only way to destroy them is by attacking them with something else, like a round plant or a coconut, or by being eaten by a Yoshi.

There are three kinds of variants, the standard variant, the bigger variant and the floating variant.
