A revival of sorts, Freaky Frog BF is modeled after an 1887 design from Central Type Foundry, called Grimaldi.

Much warmth and charm have been instilled into the original design through among other means, reworked contours and serifs. Contours are smoothened, liberated from its roughness, while serifs have become somewhat concave. Verticals and horizontals appear to “swell” owed in part to flared shapes.

The overall effect, I believe, is one of pure typographic endearment.
