In Take the Plunge: Part 2, Blocky said he didn't want to pick Spongy for the team. Later, however, Blocky picked Spongy on their team using sarcasm. This was mostly to annoy Match, as she hated Spongy. Match then asks what that was for.
In Crybaby!, Blocky appeared very happy to see Spongy at the bottom when he was falling down the bottomless pit, although this is probably because he knew that Spongy was bouncy enough for them to get back on the tightrope.
