Twilight Sparkle said to Rarity that Spike has ticklish feet, so she proceeds to have fun with him. However, due to Spike being lovestruck with Rarity, he turned out to be immune to the tickles (either that, or he is ticklish, but he's too busy looking at Rarity lovingly to notice), to Rarity's confusion. ''Twilight? I thought you said Spike has ticklish feet?'' she asked. ''But he does!'' said Twilight, confused. ''Earlier he was laughing and begging to stop before you came along!''
