Wiglin appears in shallows at Rolling Waves Park during the day (Downtown Springdale).
Befriended: "You like my wigglin'? Then let's wiggle together, why don't we?"
Receiving food (favourite):"Tasty broth!"
Receiving food (normal): "This is average."
Receiving food (disliked): "You tried..."
Freed from the Crank-a-kai: "Those who dance together stay together. Wiggle on!"
Wiglin debuts in EP013 along with Steppa and Rhyth, in which they cause Nate to be able to dance when previously was not able to. While initially grateful, Nate quickly curses this new ability when it takes him to the extreme by causing him to dance even in inappropriate situations. Some time after this, the Yo-kai Dancers give Nate their Yo-kai Medals.
In EP024, Nate summons Wiglin, Steppa, and Rhyth to make Tengloom smile. However, this plan backfires and all of them fall rolling down to a three, which ironically makes Tengloom smile.
In EP027, Wiglin, Steppa, and Rhyth are seen in Yo-kai-lifornia where they are among the Yo-kai waiting in line for the release of the Yo-kai Watch Model Zero.
He is voiced by Alicyn Packard.
"Wiglin" is a corruption of wiggling.
"Wakame-kun" comes from wakame (若布), the Undaria pinnatifida species of edible seaweed.
