Enviro-Fete '98 was an exhibition, held in the Emerald Hill Zone in 1998, featuring new inventions that are friendly to the environment.
- Roger Bodge, who presented a self-heating bathtub in which you could bathe in the same water every day;
- Tyson Dense, who presented a machine for chopping down trees at a fantastic rate; and
- Tekno the Canary, who presented a Solar-Powered Hover Scooter.
The judges awarded first prize to Tekno. Tyson Dense considered this a great insult, and chased after Tekno in his own invention, destroying a nearby forest. He was defeated when Amy Rose fired a crossbow bolt into a weak spot of his machine, destroying it and dumping Tyson himself into Roger Bodge's mouldy bathwater.
