During the 1960s and 1970s "Professor" Len Tomlinson operated one of the UK's last flea circuses in a small booth on the amusement park. The attraction consisted of harnessed human fleas racing chariots at the rate of an inch every few seconds, pulling a garden roller, riding a tricycle and "fencing fleas" scrabbling at pins stuck in pieces of cork in a semblance of a sword fight. The flea circus closed down in the late 1970s as improvements in domestic living conditions made human fleas more difficult to obtain.
