Navy's Weird Tour

Navy's Weird Tour is a standalone video posted at the end of May 2020. It features Navy fighting some floating boxes in a "Marble Siege" style.

Plot
In the very start of the video, a blue house with two floors is seen. On the bottom floor, there is nothing except for three square windows on the walls, and a couch and television in a corner of the house. The TV is on the floor. On the top room, there is a hatstand with three pegs (which only hold Navy's sailor cap), a door on the wall, and a bunk bed. The top bunk is occupied by Navy and the bottom one is occupied by the marble which is watching TV.

Navy wakes up and grabs his sailor cap and leaves home. After going downhill for a while, he encounters a Floating Box and engages on a fight with it. The battle arena is the same for all 3 fights, a plane with downward slopes at its ends, two uneven plus-shaped spinners near middle, the left one spins counter-clockwise, and the right one spins clockwise, and a speed booster pad that sends you upward, towards the boss.

The Boxes will send circles downward as attacks, and the two last ones will also shoot Navy with circles as well.

Navy fought Floating Box and won, then he fought Big Floating Box and won again, but lost against Fierce Floating Box.

After the mysterious eye from the Fancy Jail appears, Navy is shown in a comic, once again at his house, revealing that it was all a dream of his and that he should look into it later.

Mechanics
Navy's Weird Tour is based on Marble Siege #3. As such, the goal is to Navy to attack the enemy directly (instead of using attack zones) and deals damage based on his speed.

Unlike Marble Siege #3, however, there's only one marble, instead of 100. Navy also possesses a Special Meter Bar, which lets him use a special attack after it's full, he can fill it by waiting or by hitting the enemy.

Navy
Navy, as a marble, has his own stats. He has 15 Health Points (HP), and 10 Attack Points (ATK), attack points are simply a multiplier AND a cap on how much damage you can do.

When his Special Meter is full, he uses the attack 'Super Strike', engulfing himself in energy and boosting towards the foe, dealing ATK x 5, which is just 50 damage.

Floating Box
Floating Box is a plain, white box. It has 100HP.

Big Floating Box
Big Floating Box is a bright lilac box with a lavender colored angry face. It has 150HP. It's bigger than Floating Box.

Fierce Floating Box
Fierce Floating Box is a yellow box with a red eye icon on it. It emits squares like some kind of aura. It has 230HP. It's as big as Big Floating Box.

Trivia

 * Fierce Floating Box killed Navy when it had 23HP, so it couldn't unleash its 15HP Deadly Circle attack.
 * Despite the enemies being boxes, all of their attacks are circles.
 * The Fancy Jail's eye is different from its usual appearance from Algicosathlon.
 * Although the battle arena is the same in design for all 3 battles, there are cosmetic differences between the three of them:
 * vs. Floating Box is the same grassland with hills landscape seen before the fights.
 * vs. Big Box is a rocky field with a dark gray sky. The hills are replaced with a mountain.
 * vs. Fierce Box is the same rocky field, although it looks more volcanic, with the rocks and the sky taking a shade of red, and lava streams can be seen behind the mountain, the mysterious eye from Algicosathlon is also on the mountain.
