by Simon Bar Sinister when he found Eel's sewer hideout. Tap Tap the Chiseler Appearances: From Hopeless to Helpless, Tricky Trap by Tap Tap Tap Tap the Chiseler is a criminal that chisels jewelry, making them into smaller pieces of jewelry. He bears an amazing resemblance to Underdog, and Tap Tap can use this advantage to impersonate Underdog. However, unlike Underdog, he does not speak in rhyme.

At that point, Tap Tap once again disguised himself as Underdog again and broke out of jail on the same day Underdog was visiting the prison.
