Finals IV: Invitational 2019
From the Super Mario Wiki
Finals IV: Invitational 2019 is an official course in Course World in Super Mario Maker 2. It is a "standard" level published by NintendoUS, being the fourth level played during the final round of the 2019 Nintendo World Championships. It is set in the castle theme for its main area and in the snow theme for its sub-area, as well as in the Super Mario Bros. style.
The level begins with pillars dropping Icicles and slightly rising lava. After jumping on Icicles to cross some Fire Piranha Plants, Mario must hit ON/OFF Switches in succession to cross some blocks while avoiding parachuting big Boom Booms. Afterwards, Mario must carefully jump on some blocks triggered by ON/OFF Switches to grab some Pink Coins before a Skewer triggers said switches so that Mario can reach a Key Door and use a Seesaw to enter a Warp Pipe. After reaching a Checkpoint Flag, Mario must slowly traverse a Snake Block while avoiding Icicles, allowing him to jump up a slope at the end. Mario must then jump from Swinging Claw to Swinging Claw while avoiding more Icicles to reach another slope further up, then move across some Vines to a Trampoline. After jumping vertically across some Bumpers, Mario must carefully maneuver some sideways Trampolines to a Vine and more Swinging Claws, then tilt a Seesaw so that he can ride a Twister to a platform above. After entering another Warp Pipe, Mario touches another Checkpoint Flag, and is led to one final area where he must hit an ON/OFF Switch to reach a Swinging Claw and some Icicles to damage a big Bowser, and thus hit the ax to clear the level.
