Apparatus of the Pea Crab

This item first appears to be a 1.5ft radius hemisphere made of a matte black metal that is cool to the touch with a seat and control panel. Four switches, four buttons, and one joystick are set in the control, switches all in the down position, joystick and buttons in neutral position, switches able to move either up or down, buttons able to be pressed down, and joystick able to be moved up, down, left, or right. Once properly activated, it is a 1.5ft radius hemispherical cockpit with four 3ft long legs coming out of the bottom and a 4ft long tail coming out of the opposite end from the control panel. The dome appears as a 3ft tall, 1.5ft radius cylinder on top of the seat section, with a 1.5ft radius hemisphere on top of that, created a capsule in total. There is a 2ft diameter circular window in the front of the capsule, allowing forward vision and 45 degree vision to either side. There is a small square piece to the left of the control panel where lava is poured into the fuel tank. The Apparatus of the Pea Crab is a Medium object with the following statistics:

Armor Class: 18 (dome closed), +2 to pilot (dome open)
Hit Points: 33 (30+CON modifier of the creator of the Apparatus)
Speed: 35ft, 40ft swim (water), 15ft swim (lava) (0 for all if legs and tail are not extended)
Damage Immunities: acid, poison, psychic

The Apparatus requires one pilot and can seat only one small or medium creature. With the dome closed, the apparatus is airtight, watertight, and lavatight, and the pilot is immune to the adverse conditions of being inside a volcano. When the dome is closed it holds enough air for 2.5 hours. The Apparatus can go underwater up to 200ft deep, below that it takes 2d6 bludgeoning damage per minute. The Apparatus can go underlava up to 50ft deep, below that it takes 3d6 bludgeoning damage per minute. The Apparatus has a 10L tank of lava used to power the motion and magical repairs of the Apparatus. Motion consumes 1mL of lava per move.

A creature in the compartment can use an action to manipulate the controls at will. After each use, the switches stay in position, the joystick goes back to its neutral position, and a button returns to its unpressed state. Two buttons on the far left arranged vertically (Button 1 over Button 2). To the right of those buttons are three Switches arranged horizontally in line with Button 1 (Switch 1 on the left, Switch 2 in the middle, and Switch 3 on the right) and two buttons arranged horizontally in line with Button 2 (Button 3 on the left Button 4 on the right). To the right of these switches and buttons is the Joystick. On the far right is Switch 4.
