Lumberjack Dan is a mostly unseen character referenced in Whimsywood. He appears to be the "mascot" of the park, with a faded wooden cut-out of him displayed prominently next to a lumberjack-themed ride. The ride also includes a soundtrack that features a repetitive jingle about Lumberjack Dan himself.
The ride portrays a scenario in which lumberjacks entered a forest and came back to town "changed", hacking apart other residents. Lumberjack Dan is likely one of these lumberjacks or is representative of them in general.
The lyrics of Lumberjack Dan's theme song are as follows:
Lumberjack Dan
Lumberjack Dan
Cutting all the trees
Working on the land
Lumberjack Dan
Lumberjack Dan
A long day's work
for the lumberjack man
The sign is described as appearing to be a standard, clichéd lumberjack character with peeling/cracked paint and faded out facial features. It is unknown as to whether this represents the "real" Dan accurately… of if there even is a "real Dan".
