From the dust of many little shrimp-triops eggs, only one was born and my son named it "Triomignon" (Triocute), and the seeds plantation was a success, and the volcano explosions worked with delight (sodium bicarbonate + vinegar + red stain), my son was very happy from this birthday gift.
But... we gave food to the little shrimp, not too much not to kill him, we changed part of its water, it was growing, turning from white to pink and now with a twin-boom tail... but after 5 days: no one anymore, but its lifeless body. My son was sad.
He helped me to build the Sesqueagle... a 30 minutes fun build.
