Snowball is a contestant in Battle for Dream Island, the long-running animated web series created by jacknjellify that premiered on YouTube in 2010, with later seasons Battle for BFDI and The Power of Two. Fans routinely clip the show's short voice lines for soundboards and reaction memes, and this blunt 'Careful' warning is one of many repurposed for gaming edits and fail compilations. The exact episode the line comes from is not documented on this page, but the clip is published here as free to use.
