Their relationship is very similar to Blocky and Golf Ball’s. Blocky and Tennis Ball weren’t that friendly at first but from BFB 2 onward, they are occasionally on good terms as they are on the same team and both of them listen to 8-Ball as their new leader.
In “The Escape From Four”, Blocky is seen pulling Tennis Ball’s back when they along with the other contestants stand up to Four, trying to pull the eliminated contestants out of him.
Neutral interactions[]
In "Return of the Hang Glider", at the sight of Tennis Ball, Snowball, Match, and Woody being abducted, Blocky is only able to say "...um."
In "Lick Your Way to Freedom", he yells at Four, demanding for Tennis Ball and Golf Ball to be recovered. After Tennis Ball gets recovered, Blocky doesn't welcome him back as Golf Ball also needs to be recovered.
In "The Four is Lava", Tennis Ball asks Blocky and Robot Flower how they're suppose to do the challenge. Blocky thinks for a minute and starts to lean the tree back. Tennis Ball isn't impressed with Blocky's idea at first since all that did was get himself and Robot Flower stuck in a different spot, until Blocky slingshots himself away.
Episodes suggesting a conflict[]
In "Lofty", Blocky is among the crowd that laughs in the faces of Tennis Ball, Golf Ball, Firey, Coiny, and Rocky.
In "A Leg Up in the Race", Blocky is once again among the crowd that laughs in the faces of the losers, Tennis Ball, Firey, and Coiny. However, this time, he holds up a couple of signs calling them "Losers."
In "Start the Shift", Tennis Ball, along with all the other BFDIA contestants still competing, are tired of Balloony and all the other LOLers (including Blocky)'s hosting, so they try to get rid of them by recovering Spongy and flinging him at the LOL to crush it.
In "Getting Teardrop to Talk", he kills Tennis Ball when he says he's managing the team with Golf Ball.
In BFDI, Blocky and Tennis Ball's elimination is conductive. Blocky is eliminated in episode 17 (for the second time), while Tennis Ball is eliminated in the next episode.
