Recipe: undertow?

Anyone Know how to make a undertow tiki drink. Had one at a restaurant. Was made with 2 different rasberry liquors blue caraco and sour mix Thanks

Hey Motomat,
Here is the original recipe; Restaraunts can change it to make it their "own".

1/2 shot Blue Curacao
1/2 shot Raspberry schnapps

Pour schnapps, then curacao into the glass. Do not mix.
