Toy Field is an unlockable minigame in Challenge Mode of Mario Superstar Baseball, and Mario Super Sluggers. Toy Field is also a separate game mode. However, players are not able to hold a regular team game in Toy Field. In it, four players play in an indoor stadium with several buttons on the floor. The batter must hit the ball on one of the buttons, and will earn or lose coins depending on the effect of the button. The pitcher's objective is to strike the batter out. The fielder's objective is to catch the ball that the batter hits, stealing their coins. The player who has the most coins when the game ends wins.
 Mario Baseball series
 Mario Superstar Baseball
First, the players select their characters. Then, they will choose to have 10, 20, 30, 40, or 50 turns for the whole game. Then, the game starts. If the pitcher strikes out the batter, the pitcher will earn 30 coins, and bat next. If a fielder catches a ball, the fielder gets to bat next. If the caught ball is a fly ball, the fielder steals 50 coins from the batter.
Hitting the buttons on the field have various effects. 1B hit advances all runner lights one base forward, earning 10 coins plus 30 (10 from each opponent) for any RBI. 2B Hit advances the lights 2 spots forward, earning 20 coins and again 30 for all RBI. 3B Hit spaces are the same, except earning 30 coins for the base score. The HR space in center field acts as a homerun, removing every runner light and giving you 40 coins for landing there, and again 30 for all RBI scored.
? spaces start a slot wheel. If the wheel shows three Bob-ombs, then the player loses 90 coins, 30 to each opponent, and if nobody catches the ball after it lands there a random player is selected to bat. Three red shells steal 30 coins from a random player. Three blue Spiny Shells steals 100 coins with the leader. Three lightning bolts switches coin totals with the leader. Three lucky 7's changes all spaces to HR for 1 turn and gives a bat again. Three 1-UP shrooms lights up all the runner lights and earns a bat-again.
Hitting the "COIN" spaces causes many coins to appear on the field. The fielders can collect the coins for a few seconds. After that time is up, the batter gets any remaining coins.
Hitting a button right next to the back wall reveals a letter. Hitting all the letters will spell "Home Run", and the player will get a home run, earning them more coins. If the ball is not caught when a batter hits it, the batter will go again.
In Challenge mode, Toy Field last for ten turns and the player is pitted against Bowser Jr., Dry Bones, and a Red Dry Bones. If either of these three are chosen (on Bowser's Challenge Mode), one of them will be replaced by Mario.
 Mario Super Sluggers
Toy field has returned from Mario Superstar Baseball. Toy field has one Batter, and three other Outfielders and a cannon that pitches the ball to the batter. Before it pitches it, there is a roulette wheel with three different slots that affects the turn. Each slot is controlled by one of the outfielders; the outfielders tap 'A' to stop the slot they are in control of. If the slots aren't stopped, they are stopped automatically.
When the batter gets strike one, he or she will lose fifteen coins, and the other players get five. On Strike two, he or she will lose another fifteen and the other players will get another five. If the batter Strikes out, he or she will lose 90, and the outfielders gain 30.
When the ball is hit there are a few possible results:
A new feature in Toy Field is the ability to tackle each other. When the ball is caught by a fielder, there will be a timer on top of the screen that starts at three seconds. When the ball is caught, the other two fielders can tackle the fielder to steal the ball. When the three seconds are up, the fielder who has the ball will bat next. If no fielder has the ball, the previous batter will "bat again". Also, each character has a different tackle. Power characters (such as Petey Piranha, Bowser, Wario, and Donkey Kong) have a long tackle. In general, fast characters with low batting (such as Toadette, Yoshi, Baby Luigi) will have a short tackle making it difficult to tackle.
There is another new element in Toy Field. The name is King bonus; it gives bonus coins. Similar to the Bonus Star's elements in Mario Party, there are additional coins rewarded or penalized, such as for tackling the most, being tackled the most, getting nice plays the most, hitting the ball perfectly).
Every time a fielder is hit by a item, he or she loses 30 coins, and the batter gains 30.
