Allies
There are a total of 54 allies in this game, three being obtained from completing a Premium character adventure, sorted in five different rarities. Most allies can only be equipped by respective character. Each character can equip one ally initially, and can increase to a maximum of four allies as they level up.

Trinkets and Weapons
Each hero is armed with a weapon that falls within one of six categories: Swords, Darts, Wands, Bombs, Guns, or Instruments. Only one may be equipped at any time. Instrument type weapons are unique in that they have a special effect that extends to nearby towers as well as the hero using the weapon. Weapon rarities start at Uncommon. There are 92 weapons in the game, three of which come from the premium heroes.

Trinkets are items that give beneficial effects, like more damage or pierce, to the character that has it. They can also have special properties that can apply when a requirement is met, like a nearby hero or land/water/lava placement. Each hero can equip three trinkets, and can be increased to a max of ten. There are 155 trinkets in the game.

If the player doesn't want an item in their collection, have duplicates, or have unfavourable items from their wish orbs, they can shard them. Doing so gives them 10, 25, 100, 300 or 1000 shards for Common, Uncommon, Rare, Super Rare and Epic items respectively.

Tracks and Rounds
There are 56 tracks in the game. 12 of those tracks are from the premium heroes and are not able to be played unless purchased or during special events. The tracks are in sets, called adventures, in an area in Ooo. For example, Cyclops is an adventure containing three tracks located in Grasslands. Some of these can unlock things like a new hero or new sets to play on. All have a difficulty on them, out of five skulls, indicating how hard it is, with track difficulties too. There are four difficulties for each track: Normal, Hard, Extreme, and Impoppable.

There are 75 Rounds of set Bloon spawns. The rounds for the difficulties are 30, 45, 60, and 75 respectively with the exception of the Normal mode of Tree Fort Exterior, Candy Throne Room, and Enchiridion with rounds of 5, 10, and 12 respectively. Every round number of all difficulty consist of the same number of Bloon types. The only difference is the added properties and/or increased buffs of Bloons, like Camo+, Regrow+, Faster Regrow, Zombie, Ghost, Shield, Faster Bloon Speed, and Fortified+. Harder difficulties have more Bloon buffs and includes up to 5 of the listed properties.

Trivia

 * Officially, this game is also considered the first spin-off of Bloons Tower Defense 6 since it uses similar graphics for the Monkeys, Bloons, and MOABs as BTD6. Similar sound effects are also used too.
 * The music appears to be a remix of the BTD6 music, as the title screen theme is a fusion between BTD6's title theme and Adventure Time's theme.
 * This is also the only game so far to not feature the Tack Shooter, Ice Monkey and Bomb Shooter.
 * However, there are some characters that have similar attacks to those towers: Wildberry Princess and Ice King's Ice Bolt upgrade as Tack Shooter, Ice King as Ice Monkey, and C4 Charlie as Bomb Shooter.
 * The game requires iOS 11 or higher to get for Apple devices and Android 5.0 or higher for Android, but also depends on the performance of the player's device.
