This pattern stands for independence: the snail abandoning its shell.
In the maritime region, the local population is mad about this mollusc. There is even a village called 'Abobo' in the Zio prefecture, and here they celebrate the snail festival Abobozan in September each year. Snail dishes are consumed and enjoyed by the locals.
In Benin the pattern is called ‘Abobo to lé gomè’, which can be translated as ‘patience has no limits’.
