"Yoshi's Egg" is written in a font similar to that of the Yoshi's Island series, with "Yoshi's" in black and "Egg" in white with a blue outline around both, as well as some extra curves. A different trackside banner that the sponsor shared with Waluigi Grand Prix was introduced in Mario Kart Wii, which featured a black Waluigi Grand Prix logo at the bottom and "Yoshi's Egg" in the normal font but with a green outline and without the oval reading "New". The background is yellow and features a pale yellow Yoshi Egg silhouette in the middle that matches the border. Yoshi's Egg also shares a sign with Waluigi Grand Prix in Mario Kart Wii, with part of the Waluigi Grand Prix logo in a dark blue stripe at the bottom and Yoshi's Egg's green outlined logo above it. The letter "Y" in a dark green gold outlined logo appears at the top of the sign. The sign is shaped like a Yoshi Egg, being a white oval with five green spots and a gold outline. It is advertised by means of trackside banners and signs.
