Grow a Girlfriend brings comedy to your bedroom with an expandable polymer companion that grows to six times its original size in water. This flesh-toned gag gift creates laughs at bachelor parties while offering a hilariously realistic appearance that never fails to spark conversations and memorable moments.

What It Does

The expanding polymer absorbs water rapidly, transforming your small novelty companion into a full-sized conversation piece. When submerged, the material begins swelling within minutes, creating an entertaining spectacle as your "girlfriend" reaches her full potential. The flesh-tone coloring adds comedic realism while the safe polymer construction ensures multiple growth cycles without degradation or damage to the material.

Watching the transformation creates genuine surprise and laughter as the compact figure expands into something impressively larger. The polymer maintains structural integrity throughout the process, allowing the features to remain proportional during growth. Once fully expanded, your new companion displays surprising detail and realistic coloring that makes the joke even funnier for friends and party guests.

Technical Specs

  • Expands up to 600% of original size when submerged
  • Safe expanding polymer material, non-toxic formulation
  • Flesh-tone realistic coloring for comedic effect
  • Reusable through multiple shrink and growth cycles
  • Air dry completely to return to original compact size

How To Use It

Submerge your compact girlfriend in room temperature water and watch the magic begin immediately. The polymer starts absorbing water within the first few minutes, with noticeable growth occurring rapidly. Position in a clear container so everyone can witness the full transformation process as she reaches maximum size over the course of several minutes.

For maximum comedic impact, present the small version first without revealing the surprise. Once curiosity peaks, add water and step back as gasps and laughter fill the room. The growth happens steadily, building anticipation as your audience watches their new friend expand to her full impressive dimensions.

Who It Suits

Bachelor party hosts looking for memorable gag gifts will find this hits the perfect note between outrageous and harmless. Friends with great senses of humor who appreciate absurd jokes and conversation starters make ideal recipients. Office gift exchanges and adult birthday parties benefit from this kind of unexpected entertainment. Anyone dating or recently single will appreciate the lighthearted take on relationships, though avoid giving this to overly serious personalities who might not appreciate polymer-based relationship humor.

Expert Review from Our In-House Tester

Opening the package revealed something much smaller than expected - about the size of a large coin. Following the simple instructions, I filled a clear glass bowl with room temperature water and dropped her in. Within thirty seconds, I could see subtle changes beginning. The real entertainment started around the two-minute mark when the expansion became obvious to everyone watching. My friends gathered around, making jokes and taking photos as she grew steadily larger. The most impressive moment came around the five-minute mark when she reached full size - genuinely surprising even though I knew what to expect. The realistic coloring made the whole transformation hilariously absurd. Total entertainment time ran about ten minutes from start to finish, with plenty of laughs and photo opportunities throughout. Even days later, people were still talking about the "girlfriend" sitting on my kitchen counter.
