Glue Globe

From the Super Mario Wiki

A Glue Globe is an orange sphere in Wario World. When touched, Wario stuck to it, allowing him to reach otherwise inaccessible places. Some Glue Globes move, while others stay floating in the air without moving. Wario could then jump off in the direction of where he was on the globe. There are also Glue Globes that have ByeBye Balloons on them. When Wario jumps on these Glue Globes he will be sent to the start or the end of the level, depending where he is. Wario, through the game manual, says that it is very embarrasing being on Glue Globes.
