PC Play & Learn
PC Play & Learn: Learning Fun with Dan and Whizzo (commonly abbreviated to PC Play & Learn) was a series of British Point-and-click adventure educational software game produced by International Masters Publishers in association with act-two, and released throughout the early to mid-2000s, delivered as part of a subscription. In these games, you would play with four dinosaurs, Dan, his older sister, Pink's friend Delilah, and Dan's pet, Whizzo. The series would come in separate CD-ROM discs in the subscription, along with a booklet and a mini binder. The series was relatively obscure until popular YouTube user tamago2474 featured it in a video for April Fool's Day in 2018, creating a renewed interest in the series for a short period of time. Gameplay 
In the games, you would play with the dinosaur characters in the Play Zone (later the Tree House), learning basic skills like Counting, Music, Letters, and more. Along the way you would collect dinosaur egg pieces, and collecting four would grant access to a special Dinosaurs for that disc (e.g. Sportysaurus in "Let's Make Friends"). Each disc would have a different theme, like "Under the Sea". Characters
