Design a kids coding brand character/mascot

Cypher Coders

Cypher is an edtech company offering fun in-person London coding camps and clubs for children aged 5-12.
In September 2014, England implemented the Computing Curriculum for Primary Schools. Cypher aims to support schools by providing a computing curriculum program that includes lesson plans, content, access to coding environments, coding support, or full delivery of the coding portion of the curriculum.

We need a fun Cypher character/mascot that will represent and enhance the curriculum materials, making them more engaging and accessible to primary school children.
This character will be used throughout all the educational materials related to the computing curriculum such as roadmap, lesson plans and content.
Inclusivity and relatability for the target audience (primary school children aged 5-12, teachers and parents) are paramount considerations.
Ensure the design is visually appealing and pedagogically sound, balancing aesthetics and educational effectiveness to optimise the learning experience.

For now, we're looking to have 1 main character but planning to have a set of variations (emotions, poses and actions) later on.
Please design the character on its own as well as ideas of how it could be integrated with the logo (with or without the tagline).

You can use ClassDojo (edtech company) as an example of what we're trying to achieve in terms of design style and theme:
