Blocky is a red building block character from Battle for Dream Island, the animated web series created by Jacknjellify that began in 2010. He later returned in Battle for BFDI and The Power of Two, where his prankster personality made his annoyed reactions popular with fans. Clips of his growls and outbursts circulate in fan edits and soundboards as quick reaction sounds. This alternate version of his GRRRRR growl spread because it sums up his temper in a clean, short clip that works outside the original scene.
