Perhaps you remember a project called Love Unleashed that some fans organized. The project was making a massive donation to the animal welfare organization based in Valley Animals California, United States and thus gain the rights to name a facility within that organization in honor of Bill and Tom Kaulitz, including the names of the twins' commemorative plaque.
The amount that fans donated to the
organization was $ 5,000, and the glass plate with the birthday book was sent to Bill and Tom Kaulitz in Germany. Valley Animal Center also opened a plaque in honor of the twins.
