Ah, yes! The life of Rolf is filled with many truths, as told by the son of a shepherd! Listen well, Anons!
The blue hedgehog creature with the spikes is the Most Swift Beast to Ever Gallop Across Rolf's Homeland! Yes-yes!
The fox-boy with two tails? He is but the Tiny Blue Spiked One! A mere sprout!
The pink hammer-wielding she-creature? She is the Female Blue Spiked One! Do not question Rolf!
If you dare to suggest that the fox-boy is "The Male Version of Pink Hammer Girl" or that Pink Hammer Girl is "The Female Fox-Boy," then you have the brain of Rolf's Nana's prize-winning turnip! You are mad as the three-headed goat of the Old Country! Bah!
If Rolf must speak truly - and Rolf always speaks truly - the Pink Hammer Girl is the OPPOSITE Fox-Boy! The anti-twin! The shadow reflection in Rolf's well!
The red echidna who guards the shiny emerald? He is the OPPOSITE Blue Spiked One! The rival! The adversary!
The purple fire-cat from the other dimension? She is the OPPOSITE-WORLD Blue Spiked One! Yes!
The black and red brooding hedgehog? He is the DARK Blue Spiked One! The shadow twin!
The silver time-traveling fool? He is the LIGHT Blue Spiked One! The bright reflection!
This is the wisdom of Rolf!
