To mark the special occasion, keepers made the bears two enticing “ice cakes” filled with pumpkin.

To get at the tasty veg inside, Tonja and Hertha first had to break open the solid ice blocks. They knocked, rolled and scratched at the frozen cakes until they could finally tuck into the yummy contents.
