Episodes suggesting a conflict
In "Take the Plunge/Part 1", Woody screams upon seeing Blocky, then gets kicked into the air by him.
In "Insectophobe's Nightmare", a picture of the eliminated contestants shows a scared Woody being held still by Blocky so Flower can kick him.
In "The Glistening", Blocky kicks Woody into the air when finding out that he has less votes than him.
In "Take the Tower", Blocky chooses Woody to go on the bridge to the other team's tower despite Woody not actually wanting to.
In "How Loe Can You Grow?", Blocky chases Woody and then kicks him into the air. He later was about to get Woody to enter Spongy's spaceship, forgetting that he kicked him earlier.
In "Let's Raid The Warehouse", Blocky tells his team to raise their hands if they want to be receivers. Woody does so nervously, but Blocky ignores him. Blocky allows Flower to be one, since she spoke up, and gets annoyed that no one else is volunteering. Taco then points out to Blocky that Woody has had his hand up the whole time. Blocky shows he was aware and didn't pick Woody because of how meekly he was raising his hand.
On the train ride, Taco determines that Blocky has been in a bad mood because Woody got to have his way. When Taco asks what gift Woody would like, Blocky finds some spiky gloves and says Woody would like one to the face. Blocky is shocked and angered that Woody hates his cardboard box, telling Woody it was supposed to be the perfect gift for him. For the first time, Woody fights back at Blocky, making noise about the awful gift. Blocky gets angrier, calling Woody a crybaby, since Woody made them lose the challenge, and grabs him, but gets stopped by Bubble before he can do anything.
In "Let's Raid The Warehouse", Blocky shows that he remembers Woody being afraid of the color gray and bubbles, and suggests getting him a box. Likely because Blocky's spent most of the series bullying Woody, he acts noticeably indifferent to Taco complimenting him and Firey for being empathetic to Woody. When they get back home, Blocky hands Woody his gift and prematurely celebrates, thinking he would love it.

In "Who Stole Donut's Diary?", when Lollipop asks Woody what he was doing at the time the diary was stole, he decides to prank them and say he was doing sailing lessons. Blocky is amazed and happy by this, that he uses his first time being understood to prank everyone. They then proceed to high five.
