Sonic the Hedgehog: Triple Trouble

Platform game where Sonic and Tails race to grab Chaos Emeralds before Dr. Robotnik builds a super-weapon. You can play as either character, each with distinct abilities and vehicles. Sonic rides a jet skateboard through snow zones and rapids. Tails pilots the Sea Fox submarine for underwater stages. Knuckles works with Robotnik this time, and a bounty hunter named Nack the Weasel competes for the same emeralds. Levels mix speed-focused platforming with exploration segments that require using the right vehicle or character skill. The structure alternates between racing to the goal and hunting for emerald shards across varied terrain. Solid pick if you want portable Sonic with more gadgets than the Genesis games offered at the time.
