In a mixing bowl, combine the cream cheese, sour cream, garlic powder, onion powder, chives, green onions and salt to taste.

Place the mixture into a piping tool or Ziploc bag with the bottom corner cut off.

Pipe the cream cheese mixture onto the top of the cucumber slices.

Put a whole black olive onto the center of the top of each cucumber bite.

Slice the remaining olives in half lengthwise, and cut each olive half into four slices to create the spider’s legs.

Place four small legs on each side of the whole olive on the cucumber bites to form small spiders.

Serve immediately, or chill before serving if desired.
