The pink drink is basically a mix of a local favorite and a Taiwan favorite. The drinks starts off as Bandung, which is Rose Syrup mixed with sweet condensed milk. The Taiwan part is the pearls or bubble. This is from Bubble tea, basically tapioca balls in milk tea. So, now we have Bandung Bubble.
The blue drink is new to me. It is technically the same as Bandung, but blue in color. It is called Soda Gembira (Happy Soda). It is basically, some blue coloring with cream soda and sweet condense milk.
The green drink is basically green coloring mixed with cream soda (or Ice Cream Soda as it is known locally). The drink reminds my children of the melon drink you find in Japan.
