Generate a design for a classic-fit boy's hoodie with a Y2K retro vibe. The hoodie should be a pastel mint green. The main design element is a playful, cartoon-style robot character on the front, rendered in a thick-lined, sticker-like style. Use a color palette of bubblegum pink, bright yellow, and sky blue for the character. The drawstrings of the hood should be a contrasting color.
