1. An adult brown rat 350 g

   Rats emit ultrasonic giggles when tickled and come back for more — research that helped earn an Ig Nobel Prize.

2. A whole pineapple 1.2 kg

   Pineapples take nearly two years to grow, and each plant produces just one fruit at a time.

3. An adult male wild boar 90 kg

   Wild boars are thriving so well they have spread or been introduced to every continent except Antarctica.

   It held the record for largest wingspan of any aircraft until 2019, yet flew exactly once, in 1947 — for about 26 seconds.
