91

Spanien is spain
Bulgarien is bulgaria
Kroatien is croatia
Ni is nine
En is one
The thing about that is when we spilt spa-ni-en 91 shows in the end
sp-a-in.... first letter is a, in is nine spelled backwards
Bulgaria we got letter number 9 the i and letter number one.
Ni-ne also contains 91 ..right :-)
