The Dink Network

How will Dink and Skard disable a frog-bot? This question may seem funny to you but the problem is that everytime Dink and Skard kills a frog Skard says " We need to find a lone frog-bot to disable ". I cant understand why ske says this despite the frog being alone.

When you find a frog bot, talk to Shard, and then talk to the bot.
