Tarantula Riding only takes place once in Season 3 and twice in Season 4. William and Aelita have both ridden a Tarantula. Aelita rode a tarantula in Lyoko Minus One when the tarantula took her to the Way Tower of the Forest Sector (while under X.A.N.A.'s control.) Then in Season 4 William rode a Tarantula two times, the first in the missed episode Lab Rat and the second in Dog Day Afternoon.
