Monster In My Pocket was a toy franchise that released waves of, you guessed it, pocket sized plastic-monsters throughout the 90s. Several of the series included dinosaurs or near-dinosaurs, and some of the later series consisted almost solely of dinosaurs. The figures all seem to have come in at least three colour-variants, and included cards.

After four series the Monster in my Pocket line began to run out of actual monsters to make, and began to take inspiration from the real world instead. Series five was a line of ‘Super Creepies’, essentially an array of extant bugs and other creepy crawlies, and series six turned its attention to dinosaurs in 1993 – that’s the line we’re all interested in here.

Monster In My Pocket was a line of small collectible figures in bright colours, all depicting monsters of some kind. The line seems to have had several series consisting of or including prehistoric animals, and the one here, the Apatosaurus, is from Series 6, which appears to have been released in 1993, during the “Dinomania” craze that followed in Jurassic Park‘s wake.
Review: Loch Ness Monster (Monsters in My Pocket by Matchbox, Series 2)

Monsters in My Pocket was a toy franchise that started in the 80s that consisted of a series of small, rubber figures. These figures were each only a few inches tall and could each come in a variety of solid colors. What makes this toy line special is that each figure is modeled after a certain creature that exists in some sort of real culture.
