Blocky

Blocky (Or Building Block in the BFDI comics) is the fourth boss in Super Lawl Bros. Brawl:Omega & Alpha Story Mode. He appears after the player beats Yoyle Needy.

Boss Cutscene
Bubble and Gardevoir accidentally activate a trap that sends them to the TLC/LOL. They then meet Blocky in there and Blocky tries to pop Bubble with his hand but Gardevoir holds Bubble and uses Psychic on Blocky. Blocky then gets mad and challenges them to a battle.

Pin Stab
Blocky sends out Pin forcing her to stab the player. If the player is Bubble, they will be KO'd instantly because Bubbles can pop if poked by something sharp. If not Bubble, they will take damage instead.

Kick
This attack is common. Blocky will run up to the player and kicks them. This attack is possible to dodge. But be quick as his kick will occur when he's close to them.

Bowling Ball
Blocky will throw a bowling ball at the player. Not only it can damage them but it can damage HIM. Attack the bowling ball to send it back to Blocky and attack him with it. There is a rare occasion that the bowling ball will hit himself.

Aerial Tack
Blocky will float in one of the Squashy Grapes' balloons and throws a tack in the direction the player is pointing at.

End Of Boss Cutscene
Blocky flies out of the TLC/LOL and creates a hole from flying out releasing all the eliminated contestants. Gardevoir then holds Bubble and teleports out of the TLC/LOL.
