A powerful in-built fan inflates the entire dinosaur balloon in 30 seconds, making sure your toddler doesn’t have long to wait to start having fun.

Plus plenty of fun for the toddler to find themselves transformed into a dinosaur as the costume inflates! There are two types of dinosaurs to choose from – Velociraptor and Trex.

    (Size: 34″ and 43″ (approximately 1 to 4 years) | Price: $)

    Why we like it: The sound button on the belly – even though some reviewers have commented that it sounded more like a goofy elephant than a scary roar – is an absolutely favourite among the kids, giving them an opportunity to interact with the costume and play with it. Kat said ” This costume is adorable, vibrant, soft, and I was impressed with the quality compared to most other ‘bag costumes’. Love the tail…it waddled back and forth as my son was running around!”

Why imaginative play with dinosaur costumes are great

Encourage spontaneity & creativity

Imaginative play, or role play, is when a child uses their imagination live out a make-believe scenario they have either experienced or would like to experience. These kind of open-ended, unstructured play is often fun and spontaneous, with no expectation of specific results and goals.

Develop social-emotional resilience

Imaginative play is crucial in helping a child learn, not just creativity, but also the ability to socially bond with others. It teaches them to respect others, communicate and build a strong foundation for social-emotional resilience.

Promotes psychological safety & bonding

Costumes are great because they signal to the child that it is “pretend” time, and allow the child the feeling of psychological safety in order to act as silly as they’d like, knowing they wouldn’t be reprimanded for not acting “as they should be” (think howling like a wolf or crawling like a snake).


Dinosaur costumes are the perfect role-playing companion for Halloween, school plays and play dates. It is a fun and safe option for many events, and is featured in many children stories like Ten Little Dinosaurs, Peppa Pig: George and the Dinosaur and The Dinos on the Bus which means you can even dress up during story time. In short, dinosaur costumers make a great gift for a toddler and the chance to play out a magnificent character will surely delight any child.
