Throw blocks look like blueish Turn blocks. Mario can pick up these blocks to activate them. Then he can carry, put down, and throw these blocks to complete a variety of tasks. Throw blocks kill most enemies on contact, and can take out a whole line of opponents. They can also be used to hit other blocks to activate their effects from a distance. Throw blocks will shatter upon contact with a select few sprites and most solid objects, and will disappear in a puff of smoke if active for too long. The only time they're used is in the Big Boo Boss battles and Valley of Bowser 1.
- Mario can jump off of a throw block while still grabbing it if both A/B and X/Y are pressed on the same frame.
- When a throw block is carried through a pipe, the timer for when it disappears will stop, and you can carry it for as long as you want.
- If a throw block is picked up on the frame the Big Boo Boss battle ends, Mario will end up floating in midair at the end.
- After a throw block is thrown, Mario can spinjump off of it.
