Seesaw

Seesaws are a type of platform objects that appear in many Mario games, and usually tilt left or right depending on where the player and/or enemies walk on it.

Super Mario Maker 2
Seesaws appears as a course element in Super Mario Maker 2. They appear as orange platforms in the Super Mario World style, and red in all other styles, and retain most of their characteristics from previous appearances. In the Super Mario Bros., Super Mario Bros. 3, and Super Mario World styles, they appear to be metallic, but in the New Super Mario Bros. U style, they are wooden. Like normal Lifts, their length can be changed, and they can be placed on tracks.

Seesaws can be abruptly tilted when a Thwomp falls on one side, throwing any playable characters and objects on the other side high into the air. This can also be achieved if a player Ground Pounds on the Seesaw (requiring a Dry Bones Shell or big Goomba's Shoe to do so in the Super Mario Bros. and Super Mario Bros. 3 styles). Furthermore, Bowser can perform this as well in the Super Mario Bros. 3 style using his Ground Pound attack.

Course elements have different weights. Twisters weigh nothing, while Spiny Shells, Buzzy Shells, Dry Bones Shells, Beach Koopas, and Koopa Shells weigh half a normal object. All players, regardless of their power-ups, weigh the same. Munchers, Thwomps, Wigglers, Bill Blasters, Cannons, Goomba's Shoes, Boom Boom, Bowser Jr., Bowser, Big Mushrooms, 10-Coins, and their variants weigh double. In addition, applying the Super Mushroom modifier to a course element doubles its weight.
