Does the look of the DKC series match the gameplay?

[Kriven]

while the water...shark thing (dunno its name)

Enguarde the Swordfish?

(there's also Rattler the Snake and Winky the Frog, both of whom enhance your jumping to super proportions, Squawks, who can fly and shoot eggs depending on color [I think the purple one is technically not Squawks... Quawks, I think...], Ellie the Elephant who can suck up water to shoot or pull in barrels from a limited distance... a few others)

Rambi and Enguarde both enhance the Kongs' offensive capabilities as well.

I wouldn't count them as power-ups, though... I mean, unless we're considering SMW Yoshi a power-up.
